I have a google script with the following code:
function hoursBetween(fromDate, toDate) {
var dates = initializeDates();
var from = dates[fromDate];
var to = dates[toDate];
var workCals = CalendarApp.getCalendarsByName('Work');
var workCal = workCals[0];
var events = workCal.getEvents(from, to);
var predictedMonthlyHours = 0;
for (var i = 0; i < events.length; i++) {
var event = events[i];
var startTime = event.getStartTime();
var endTime = event.getEndTime();
var duration = endTime - startTime;
duration = parseFloat(duration/(3600*1000));
duration -= dates['break'];
predictedMonthlyHours += duration;
}
return predictedMonthlyHours;
}
I have ran in the script editor with no problems (it asked for auth and I accepted)
When I try to call the function from my spreadsheet I get the following error:
"You do not have permission to call getCalendarsByName"
I have also tried adding triggers with no result.
How are you trying to call from spreadsheet?
If you're trying to call via a spreadsheet formula =hoursBetween(), then it won't work. See Custom Functions..."Unlike most other types of Apps Scripts, custom functions never ask users to authorize access to personal data. Consequently, they can only call services that do not have access to personal data,"
Other options to set the cell value:
manual button click in a sidebar Add-on
manual click on a custom menu option
install a timed trigger to run automatically
Because the method is looking for multiple "Calendars" it's returning an array of calendars. So if you have only one calendar named "Work", you still need to call it and pick which one it is. So try changing the variable "workCals" to `
var workCals = CalendarApp.getCalendarsByName('Work')[0];
Adding the [0] will pick the first one available.
With out seeing the rest of the code, hard to decipher.

I have an app script for Google Sheets that works when I trigger it manually, but I would like it to be time driven, running automatically once an hour. I've tried setting that up using the Apps Script UI, and it looked like this:
Trigger
But I consistently get this error message:
Exception: Cannot call SpreadsheetApp.getUi() from this context.
at unknown function
I also tried writing the time trigger into the script, but kept getting an error. Here's the current script, which does work fine when I trigger it manually.
var ui = SpreadsheetApp.getUi();
function onOpen(e){
ui.createMenu("Gmail Manager").addItem("Get Emails by Label", "getGmailEmails").addToUi();
}
function getGmailEmails(){
var label = GmailApp.getUserLabelByName('EmailsToBeExported');
var threads = label.getThreads();
for(var i = threads.length - 1; i >=0; i--){
var messages = threads[i].getMessages();
for (var j = 0; j <messages.length; j++){
var message = messages[j];
extractDetails(message);
}
threads[i].removeLabel(label);
}
}
function extractDetails(message){
var dateTime = message.getDate();
var subjectText = message.getSubject();
var senderDetails = message.getFrom();
var bodyContents = message.getPlainBody();
var activeSheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
activeSheet.appendRow([dateTime, senderDetails, subjectText, bodyContents]);
}`
You can not use SpreadsheetApp.getUi() from a time driven trigger. Change you triggers to:
You can also maintain the usability by altering the code like so:
try {
const UI = SpreadsheetApp.getUi();
} catch (err) {
const UI = {
alert: function() {return;},
prompt: function() {return true;},
button: {YES: false},
ButtonSet: {YES_NO: false}
}
}
You'll have to set parameters for the UI manually, but what it does it makes it so that your code runs and handles things as you expect.
I specifically put the prompt as true and the buttons as false. That way, if I am checking if they are equal to a specific button, it will always evaluate false.
e.g.
var result = UI.prompt("Some title", "Some question", UI.ButtonSet.YES_NO);
if (result == UI.Button.YES) {//always false
//This part does not evaluate
}
You'd have to make sure that you can do this consistently throughout your script. You may like to change the assignments of the values (depending on your conditional statements) to strings, numbers, or other unique things, or change your conditional statements to include "===" instead, etc. The prompts are the trickiest ones. With this change in code, you can have the UI prompts and alerts when you run the script from within Google Sheets. It will skip them when you run it from outside, such as timed executions or other things that would activate your script externally.
I've created a Google Sheet with an Apps Script to do issue and task tracking. One of the features I'm trying to implement is permissions based assigning of tasks. As a precursor to that, I have a hidden sheet populated with a list of users and their file permissions, using code similar to that in this StackOverflow question
When I manually run the code, it works fine. However, I want it to load every time the sheet is opened in case of new people entering the group or people leaving the group. So I made a call to my function in my onOpen simple trigger. However, when it is called via onOpen, I get the following:
GoogleJsonResponseException: API call to drive.permissions.list failed with error: Login Required
at getPermissionsList(MetaProject:382:33)
at onOpen(MetaProject:44:3)
Here are my functions:
My onOpen Simple Trigger:
function onOpen() {
//Constant Definitions for this function
const name_Access = 'ACCESS';
const row_header = 1;
const col_user = 1;
const col_level = 2;
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sht_Access = ss.getSheetByName(name_Access);
var ui = SpreadsheetApp.getUi();
ui.createMenu('MetaProject')
.addSubMenu(
ui.createMenu('View')
.addItem('Restore Default Sheet View', 'restoreDefaultView')
.addItem('Show All Sheets', 'showAllSheets')
)
.addSeparator()
.addToUi();
//Clear Contents, Leave Formatting
sht_Access.clearContents();
//Set Column Headers
var head_name = sht_Access.getRange(row_header,col_user);
var head_level = sht_Access.getRange(row_header,col_level);
head_name.setValue('User');
head_level.setValue('Level');
//Refresh User List for use in this instance
getPermissionsList();
}
Here is getPermissionsList:
function getPermissionsList() {
const fileId = "<REDACTED>"; // ID of your shared drive
const name_Sheet = 'ACCESS';
const row_start = 2;
const col_user = 1;
const col_access = 2;
var ss = SpreadsheetApp.getActiveSpreadsheet();
var thissheet = ss.getSheetByName(name_Sheet);
// THIS IS IMPORTANT! The default value is false, so the call won't
// work with shared drives unless you change this via optional arguments
const args = {
supportsAllDrives: true
};
// Use advanced service to get the permissions list for the shared drive
let pList = Drive.Permissions.list(fileId, args);
//Put email and role in an array
let editors = pList.items;
for (var i = 0; i < editors.length; i++) {
let email = editors[i].emailAddress;
let role = editors[i].role;
//Populate columns with users and access levels / role
thissheet.getRange(row_start + i,col_user).setValue(email);
thissheet.getRange(row_start + i,col_access).setValue(role);
}
I searched before I posted and I found the answer via some related questions in the comments, but I didn't see one with an actual answer. The answer is, you cannot call for Permissions or anything requiring authorization from a Simple Trigger. You have to do an Installable trigger.
In order to do that do the following:
Create your function or rename it something other than "onOpen".
NOTE: If you name it onOpen (as I originally did and posted in this answer) it WILL work, but you will actually run TWO triggers - both the installable trigger AND the simple trigger. The simple trigger will generate an error log, so a different name is recommended.
Click the clock (Triggers) icon on the left hand side in Apps Script.
Click "+ Add Trigger" in the lower right
Select the name of your function for "which function to run"
Select "onOpen" for "select event type"
Click "Save".
The exact same code I have above now runs fine.
I have built a simple custom function in Apps Script using URLFetchApp to get the follower count for TikTok accounts.
function tiktok_fans() {
var raw_data = new RegExp(/("followerCount":)([0-9]+)/g);
var handle = '#charlidamelio';
var web_content = UrlFetchApp.fetch('https://www.tiktok.com/'+ handle + '?lang=en').getContentText();
var match_text = raw_data.exec(web_content);
var result = (match_text[2]);
Logger.log(result)
return result
}
The Log comes back with the correct number for followers.
However, when I change the code to;
function tiktok_fans(handle) {
var raw_data = new RegExp(/("followerCount":)([0-9]+)/g);
//var handle = '#charlidamelio';
var web_content = UrlFetchApp.fetch('https://www.tiktok.com/'+ handle + '?lang=en').getContentText();
var match_text = raw_data.exec(web_content);
var result = (match_text[2]);
Logger.log(result)
return result
}
and use it in a spreadsheet for example =tiktok_fans(A1), where A1 has #charlidamelio I get an #ERROR response in the cell
TypeError: Cannot read property '2' of null (line 6).
Why does it work in the logs but not in the spreadsheet?
--additional info--
Still getting the same error after testing #Tanaike answer below, "TypeError: Cannot read property '2' of null (line 6)."
Have mapped out manually to see the error, each time the below runs, a different log returns "null". I believe this is to do with the ContentText size/in the cache. I have tried utilising Utilities.sleep() in between functions with no luck, I still get null's.
code
var raw_data = new RegExp(/("followerCount":)([0-9]+)/g);
//tiktok urls
var qld = UrlFetchApp.fetch('https://www.tiktok.com/#thisisqueensland?lang=en').getContentText();
var nsw = UrlFetchApp.fetch('https://www.tiktok.com/#visitnsw?lang=en').getContentText();
var syd = UrlFetchApp.fetch('https://www.tiktok.com/#sydney?lang=en').getContentText();
var tas = UrlFetchApp.fetch('https://www.tiktok.com/#tasmania?lang=en').getContentText();
var nt = UrlFetchApp.fetch('https://www.tiktok.com/#ntaustralia?lang=en').getContentText();
var nz = UrlFetchApp.fetch('https://www.tiktok.com/#purenz?lang=en').getContentText();
var aus = UrlFetchApp.fetch('https://www.tiktok.com/#australia?lang=en').getContentText();
var vic = UrlFetchApp.fetch('https://www.tiktok.com/#visitmelbourne?lang=en').getContentText();
//find folowers with regex
var match_qld = raw_data.exec(qld);
var match_nsw = raw_data.exec(nsw);
var match_syd = raw_data.exec(syd);
var match_tas = raw_data.exec(tas);
var match_nt = raw_data.exec(nt);
var match_nz = raw_data.exec(nz);
var match_aus = raw_data.exec(aus);
var match_vic = raw_data.exec(vic);
Logger.log(match_qld);
Logger.log(match_nsw);
Logger.log(match_syd);
Logger.log(match_tas);
Logger.log(match_nt);
Logger.log(match_nz);
Logger.log(match_aus);
Logger.log(match_vic);
Issue:
From your situation, I remembered that the request of UrlFetchApp with the custom function is different from the request of UrlFetchApp with the script editor. So I thought that the reason for your issue might be related to this thread. https://stackoverflow.com/a/63024816 In your situation, your situation seems to be the opposite of this thread. But, it is considered that this issue is due to the specification of the site.
In order to check this difference, I checked the file size of the retrieved HTML data.
The file size of HTML data retrieved by UrlFetchApp executing with the script editor is 518k bytes.
The file size of HTML data retrieved by UrlFetchApp executing with the custom function is 9k bytes.
It seems that the request of UrlFetchApp executing with the custom function is the same as that of UrlFetchApp executing withWeb Apps. The data of 9k bytes are retrieved by using this.
From the above result, it is found that the retrieved HTML is different between the script editor and the custom function. Namely, the HTML data retrieved by the custom function doesn't include the regex of ("followerCount":)([0-9]+). By this, such an error occurs. I thought that this might be the reason for your issue.
Workaround:
When I tested your situation with Web Apps and triggers, the same issue occurs. By this, in the current stage, I thought that the method for automatically executing the script might not be able to be used. So, as a workaround, how about using a button and the custom menu? When the script is run by the button and the custom menu, the script works. It seems that this method is the same as that of the script editor.
The sample script is as follows.
Sample script:
Before you run the script, please set range. For example, please assign this function to a button on Spreadsheet. When you click the button, the script is run. In this sample, it supposes that the values like #charlidamelio are put to the column "A".
function sample() {
var range = "A2:A10"; // Please set the range of "handle".
var raw_data = new RegExp(/("followerCount":)([0-9]+)/g);
var sheet = SpreadsheetApp.getActiveSheet();
var r = sheet.getRange(range);
var values = r.getValues();
var res = values.map(([handle]) => {
if (handle != "") {
var web_content = UrlFetchApp.fetch('https://www.tiktok.com/'+ handle + '?lang=en').getContentText();
var match_text = raw_data.exec(web_content);
return [match_text[2]];
}
return [""];
});
r.offset(0, 1).setValues(res);
}
When this script is run, the values are retrieved from the URL and put to the column "B".
Note:
This is a simple script. So please modify it for your actual situation.

Added:
About the following additional question,
whilst this works for 1 TikTok handle, when trying to run a list of multiple it fails each time, with the error TypeError: Cannot read property '2' of null. After doing some investigating and manually mapping out 8 handles, I can see that each time it runs, it returns "null" for one or more of the web_content variables. Is there a way to slow the script down/run each UrlFetchApp one at a time to ensure each returns content?
i've tried this and still getting an error. Have tried up to 10000ms. I've added some more detail to the original question, hope this makes sense as to the error. It is always in a different log that I get nulls, hence why I think it's a timing or cache issue.
In this case, how about the following sample script?
Sample script:
In this sample script, when the value cannot be retrieved from the URL, the value is tried to retrieve again as the retry. This sample script uses the 2 times as the retry. So when the value cannot be retrieved by 2 retries, the empty value is returned.
function sample() {
var range = "A2:A10"; // Please set the range of "handle".
var raw_data = new RegExp(/("followerCount":)([0-9]+)/g);
var sheet = SpreadsheetApp.getActiveSheet();
var r = sheet.getRange(range);
var values = r.getValues();
var res = values.map(([handle]) => {
if (handle != "") {
var web_content = UrlFetchApp.fetch('https://www.tiktok.com/'+ handle + '?lang=en').getContentText();
var match_text = raw_data.exec(web_content);
if (!match_text || match_text.length != 3) {
var retry = 2; // Number of retry.
for (var i = 0; i < retry; i++) {
Utilities.sleep(3000);
web_content = UrlFetchApp.fetch('https://www.tiktok.com/'+ handle + '?lang=en').getContentText();
match_text = raw_data.exec(web_content);
if (match_text || match_text.length == 3) break;
}
}
return [match_text && match_text.length == 3 ? match_text[2] : ""];
}
return [""];
});
r.offset(0, 1).setValues(res);
}
Please adjust the value of retry and Utilities.sleep(3000).
This works for me as a Custom Function:
function MYFUNK(n=2) {
const url = 'my website url'
const re = new RegExp(`<p id="un${n}.*\/p>`,'g')
const r = UrlFetchApp.fetch(url).getContentText();
const v = r.match(re);
Logger.log(v);
return v;
}
I used my own website and I have several paragraphs with ids from un1 to un7 and I'm taking the value of A1 for the only parameter. It returns the correct string each time I change it.
I have been puzzling this over for some time and have searched extensively, but found no solution.
I'm using Google Apps Script and I run events for a large organization and we have about 80 different registration Google Forms for these events. I want to get the registrant's email address and send them an email when they submit their form. This is easy to accomplish by setting up each individual form. Ideally, I would set up the onSubmit trigger for the form and then copy that form for each new event. However, it seems you cannot install a trigger programmatically without going to the form and running the script manually, and then authorize it. When a form is copied it also loses all its triggers. Am I wrong about this? Doing this for each form is not realistic given that events are added all the time and I have other responsibilities.
Is there no way to set a trigger for these files without running and authorizing each one?
My other solution is:
I am trying to get all the forms in a folder and then get the responses and send a single email to each registrant. This seems overly complicated and requires checking all the forms regularly since there are no triggers for the individual forms. I tried setting triggers in my spreadsheet for the forms and this works, but the number of triggers for a spreadsheet is limited to 20, so doesn't work here. Running my script every minute and then checking if an email has been sent to each respondent seems possible, but complex and possibly prone to errors...
Thanks for any help you can offer!
pgSystemTester's answer worked for me.
I added two bits of code.
One, to declare the time stamp value to zero if there wasn't one
there.
Two, the code needed a "-1" when you get dRange or you insert a new
row which each run.
function sendEmailsCalendarInvite() {
const dRange = sheet.getRange(2, registrationFormIdId, sheet.getLastRow() - 1, 2);
var theList = dRange.getValues();
for (i = 0; i < theList.length; i++) {
if (theList [i][1] == ''){
theList[i][1] = 0;
}
if (theList[i][0] != '') {
var aForm = FormApp.openById(theList[i][0]);
var latestReply = theList[i][1];
var allResponses = aForm.getResponses();
for (var r = 0; r < allResponses.length; r++) {
var aResponse = allResponses[r];
var rTime = aResponse.getTimestamp();
if (rTime > theList[i][1]) {
//run procedure on response using aForm and aResponse variables
console.log('If ran')
if (rTime > latestReply) {
//updates latest timestamp if needed
latestReply = rTime;
}
//next reply
}
}
theList[i][1] = latestReply;
//next form
}
}
//updates timestamps
dRange.setValues(theList);
}
This is probably a simple solution that will work. Setup a spreadsheet that holds all Form ID's you wish to check and then a corresponding latest response. Then set this below trigger to run every ten minutes or so.
const ss = SpreadsheetApp.getActiveSheet();
const dRange = ss.getRange(2,1,ss.getLastRow(),2 );
function loopFormsOnSheet() {
var theList = dRange.getValues();
for(i=0;i<theList.length;i++){
if(theList[i][0]!=''){
var aForm = FormApp.openById(theList[i][0]);
var latestReply = theList[i][1];
var allResponses = aForm.getResponses();
for(var r=0;r<allResponses.length;r++){
var aResponse = allResponses[r];
var rTime = aResponse.getTimestamp();
if(rTime > theList[i][1]){
//run procedure on response using aForm and aResponse variables
if(rTime >latestReply){
//updates latest timestamp if needed
latestReply=rTime;
}
//next reply
}
}
theList[i][1] = latestReply;
//next form
}
}
//updates timestamps
dRange.setValues(theList);
}
I am trying to write a Google Apps script to modify calendar events so I have modified an example to list events first. When I try debugging this it reports an error that "Calendar is not defined" on the line "events = Calendar.Events.list(calendarId, options);"
I have enabled the advanced calendar API, and am basing my script on one from the Google documentation, so I assume that one worked. Is there anything else I need to do to access the relevant objects and methods?
/*
Adapted from code in https://developers.google.com/apps-script/advanced/calendar
*/
function syncColourCode() {
var calendarId = CalendarApp.getDefaultCalendar();
var properties = PropertiesService.getUserProperties();
var fullSync = properties.getProperty('fullSync'); // sync status is stored in user properties
var options = {
maxResults: 100
};
var syncToken = properties.getProperty('syncToken'); // pointer token from last sync also stored in user properties
if (syncToken && !fullSync) { // if there is a sync token from last time and sync status has not been set to full sync
options.syncToken = syncToken; // adds the current sync token to the list of sync options
} else {
// Sync events from today onwards.
options.timeMin = new Date().toISOString(); //change to new Date().toISOString() from getRelativeDate(-1, 0).toISOString()
}
// Retrieve events one page at a time.
var events;
var pageToken;
do {
try {
options.pageToken = pageToken;
events = Calendar.Events.list(calendarId, options);
} catch (e) {
Not a google-apps expert, but from reviewing the code, I see a possible problem. At no point do I see your code checking to see if getDefaultCalendar() actually returned a valid calendar ID. Later your code uses that ID under the assumption that it is good. Have you checked the value of calendarId that is returned?
Sometimes you have to read a little deeper into the message, but I always try to start with trusting the error return. In this case "Calendar is not defined" makes me question the value of calendarId.
It seem that Google made some change so that there is no Calendar reference from the AppScript API.
Anyway to get the event you may use this API:
CalendarApp.getEvents(startTime, endTime)
https://developers.google.com/apps-script/reference/calendar/calendar-app#geteventsstarttime-endtime
Below are my example function running within google sheet.
function listEventsWithinTwoMonth(){
var calendar = CalendarApp.getDefaultCalendar();
var spreadsheet = SpreadsheetApp.getActiveSheet();
var now = new Date();
var twoMonthFromNow = new Date(now.getTime() + (24 * 60 * 60 * 30 * 4 * 1000));
var events = calendar.getEvents(now, twoMonthFromNow);
if (events.length > 0) {
// Header Rows
spreadsheet.appendRow(["#่","id","StartTime","EndTime","Title","Description"]);
for (i = 0; i < events.length; i++) {
var event = events[i];
Logger.log("" + (i+1) + event.getId() +" "+ event.getStartTime()+" "+event.getEndTime()+" "+event.getTitle()+" "+event.getDescription())
spreadsheet.appendRow([(i+1),event.getId(),event.getStartTime(),event.getEndTime(),event.getTitle(),event.getDescription()]);
}
} else {
Logger.log('No upcoming events found.');
}
}
Hope this help.
CalendarApp.getDefaultCalendar() retrieves an object of the class Calendar that has multiple properties, among others an Id.
To retrieve the calendar Id, you need to define
var calendarId = CalendarApp.getDefaultCalendar().getId();
