I suppose my question is twofold: doGet() in the following context will just fail after 0.1~0.2 seconds without posting logs, so I have no idea how to troubleshoot it by myself. Additionally, if I'm having the script execute on my behalf, do I have to push a request with my authorization token to a more "pertinent" area than just the sheet name, such as within the iteration itself? Read further for more details:
I have a source spreadsheet where I am cross-referencing user inputted data to validate the information we have "on file". Most of our clients are over the age of 55, so I am trying to reduce end-user complexity by having the script run on my behalf whenever they need to use it (to bypass the Authorization screen, with the big scary "This application could be unsafe!" message). The way I've read to accomplish this seems to be with doGet(), so I set up a low-level HTTP Get request that just pushes a doGet() with my OAuth token, returning the sheet name. I also set up a masking function specifically to do this, and linked it to the button originally used for the iteration logic. The doGet() looks like this:
const doGet = e => {
Logger.log(`Recieved HTTP request.`);
const content = ContentService.createTextOutput(iterator(e));
Logger.log(content);
return content;
}
and the button that uses UrlFetchApp looks like:
const runMask = () => {
const active = SpreadsheetApp.getActiveSheet().getSheetName();
const v4 = 'https://script.google.com/macros/s/<scriptid>/dev' // ScriptApp.getService().getUrl() posts 404
UrlFetchApp.fetch(`${v4}?sheetName='${active}'`, {
headers: { Authorization: `Bearer ${ScriptApp.getOAuthToken()}` },
});
I have some logs set up within the real runMask() that proceed all the way to the end of the program, giving me real URLs and OAuth tokens, so I know it's making it through runMask() without an issue. However, the doGet() log doesn't post anything, even at the top of the function. I can see that it's executing the trigger in my execution log, but the log itself remains empty.
I've tried:
using ScriptApp.getService().getUrl() in place of v4: posts 404 in the log w/ truncated server response
replacing ${active} with the name of the sheet: same issue; logging ${active} also returns the correct name of the sheet.
Beyond this, I'm not even sure what to do. I have everything scoped correctly (auth/spreadsheets.currentonly, auth/script.external_request, and auth/userinfo.email), and I have no issues about operational security (as both the spreadsheet and script are written by me, the clients have no need to grant access to their entire drive). Before trying to implement doGet() and bypass the authorization screen, the iterator itself worked just fine. As such, I have chosen not to include it here, as it's hardly relevant (the function that executes the iteration function never makes it to that point).
I understand this has been quite the deluge of information; I'd be happy to provide more information or context as needed.
Getting ReferenceError: iterator is not defined (line 12, file "ag2")
With this:
const doGet = e => {
Logger.log(`Recieved HTTP request.`);
const content = ContentService.createTextOutput(iterator(e));
Logger.log(content);
return content;
}
Issued with url/exec?option=A
It runs with
const doGet = e => {
Logger.log(`Recieved HTTP request.`);
const content = ContentService.createTextOutput(JSON.stringify(e));
Logger.log(content);
return content;
}
and returns the appropriate stringified object
Only use the test URL (/dev) for testing the web app from a web browser.
Before doGet from a web browser using a versioned deployment (/exec) remember to publish a new version.
Assign a Google Cloud Project to your Google Apps Script project. For details see https://developers.google.com/apps-script/guides/cloud-platform-projects.
To make it easier to debug your avoid calling functions from a Google Apps Script method like createTextOutput, instead, assign the function result to a variable and use it as the method parameter, i.e. replace
const content = ContentService.createTextOutput(iterator(e));
by
const something = iterator(e);
const content = ContentService.createTextOutput(something);
For debugging purposes, create a function to call your doGet function, and check that it hasn't any problem to run, i.e.
function __test__doGet(){
const e = {
parameter: {}
}
doGet(e);
}

Issue:
When I saw your question, I'm worried about I have everything scoped correctly (auth/spreadsheets.currentonly, auth/script.external_request, and auth/userinfo.email).
If you are using only the following scopes at oauthScopes of appsscript.json,
https://www.googleapis.com/auth/spreadsheets.currentonly
https://www.googleapis.com/auth/script.external_request
https://www.googleapis.com/auth/userinfo.email
Unfortunately, these scopes cannot be used for access to Web Apps. Although I'm not sure about the method for running your function of runMask, I thought that this might be the reason for your issue.
Solution:
If you want to access Web Apps of https://script.google.com/macros/s/<scriptid>/dev using the access token retrieved by ScriptApp.getOAuthToken(), please include the following scope.
https://www.googleapis.com/auth/drive.readonly
or
https://www.googleapis.com/auth/drive
After you include the above scope, please reauthorize the scopes, and test it again. When your function of iterator has already been declared and the script worked, by running runMask, you can see the log of Logger.log(Recieved HTTP request.) and Logger.log(content) at the log.

I tried to login my account by using UrlFetchApp, when I ran script manually, everything worked well. But when I set trigger to run automatically, it returned "error_need_ivs". I have no idea what it is and how to fix. please help me. Below is my code
function login() {
var data = {
'username':'username',
'password_hash':'password',
}
var option = {
muteHttpExceptions: true,
"method" : "POST",
"payload" : data,
}
var url = 'my url'
var res = JSON.parse(UrlFetchApp.fetch(url,option).getContentText());
Logger.log(res) //returned error_need_ivs when I set trigger but worked well when I ran script manually
}
UPDATE : This picture show the result after scripting executed by trigger
From the new screenshot shared I can see no Exceptions were thrown, which means the error logged error_need_ivs certainly comes from the response of the HTTP request rather than an issue with Apps Scripts.
Regarding why it works when calling the affected function manually and why it doesn't worked when invoking it via timed-trigger, I believe what #Tanaike suggested to make sense, maybe the affected endpoint is not prepared to receive IPv6 requests or require more data when doing so.
I'd suggest checking the documentation for the endpoint you are making the request for to help identify what might be causing this behavior.
Alternatively, I'd also suggest to report it as an Issue on IssueTracker using this template. Make sure to include a full reproducible scenario when reporting it (including a working endpoint).
I'm trying to set a user's OU from an App Script inside App Maker.
(user is a variable with an email address)
function getUser(user) {
var x = AdminDirectory.Users.update(
{
orgUnitPath: "/",
userKey: user,
});
console.log("function ran");
}
This code errors with:
Exception: Invalid number of arguments provided. Expected 2-3 only at getUser (ServerScripts:107)
Invalid number of arguments provided. Expected 2-3 only
at getUser (ServerScripts:107)

What am I doing wrong here? Looking at the docs, you only need to provide the properties you're changing.
The Apps Script documentation says the following:
For detailed information on this service, see the reference documentation for the Admin SDK Directory API. Like all advanced services in Apps Script, the Admin SDK Directory service uses the same objects, methods, and parameters as the public API.
Therefore, we need to consult the documentation to get clarification on how to achieve this.
The method requires at least two parameters: that means that the the first parameter is a user object resource and the second parameter is the email address of the user: AdminDirectory.Users.update(resource, userKey). So you need to do this:
function getUser(user) {
var userResource = {
orgUnitPath: "/"
};
var updated = AdminDirectory.Users.update(userResource, user);
console.log(updated.primaryEmail);
}
So why do you need to specify the user email in the method when it is already being specified in the userResource object? Well, the email address in the userResource object would be the new value, in case you want to change the email address.
P.S. Perhaps you might wanna change the name of the function to something that is more of a match; updateUser() perhaps? I hope this helps!
Is it possible to reference GmailApp in a my_custom_js.html file, as opposed to the Code.gs file?
The following works when used in Code.gs:
// BEGIN email
// define email recipients
var email_recipient = uploader_email;
// Email subject
var subject = "Form submitted"
// Email body
var body = my_html;
Logger.log(email_recipient);
// Send email
GmailApp.sendEmail(email_recipient, subject, body);
// END email
But it doesn't work when used in a function in my_custom_js.html.
Developer Tools > Console shows error:
Uncaught ReferenceError: Logger is not defined
Uncaught ReferenceError: GmailApp is not defined
The reason I want it to run in the custom script, is that it utilises:
// BEGIN handle form submit
function handleFormSubmit(formObject) {
google.script.run.withSuccessHandler(updateUrl).processForm(formObject);
}
// END handle form submit
And, if I understand that code correctly, updateUrl is only running after a successful operation - so I'd like to send the email from the updateUrl() function (ie after a successful operation).
Perhaps I need to use something like a scriptlet , but for use in js files?
Edit
I'm looking into:
https://developers.google.com/apps-script/guides/html/reference/run
And will see if I can pass through the values to a function defined in Code.gs using the following in my_custom_js.html:
google.script.run.sendNotificationEmail(arg1,arg2);
Edit
That last idea worked, but would appreciate any insight on the original question, thanks.
This week for the first time I have been using Google's realatively new Javascript Client API. Using this api you could trigger your Google apps script to run from any custom website and get a callback with the result from any methods you would normally use with in the appscript. It took a bit of fiddling to get it to work, including setting up things in API console, but it's so cool you can run and call and trigger any appscript from anywhere.
In this post, I suggested to use the ScriptDB as an intermediate storage for global data of a Container Extension code. I wrote a sample code for my answer but the sample throws the error: You do not have permission to call query (line X) exception in a ScriptDb.getMyDb().query(...); line. I created the following simpler example demonstrating the problem. The code, both getDBSize and getSource functions, is permitted to use the ScriptDB by running it in the editor. The getDBSize function is executed without any problem by pressing the Run button in the Spreadsheet Script Manager Dialog. The getSource function works everywhere.
I published the Spreadsheet for the example - link. It is impossible to share the code for view, but it is possible to output it in a cell, the cell B3 contains exactly bellow code.
How is possible to permit the Spreadsheet Code to have access to the ScriptDB?
function getDBSize() {
var db = ScriptDb.getMyDb();
var result = db.query({});
var count = result.getSize();
return count;
}
function getSource() {
return this.toSource();
}
The problem is that you're trying to run this function as a spreadsheet custom function, and custom functions are way more limited than all examples on the Container Extension page you linked.
But, from a theoretical point of view, custom functions as well as simple event handlers (e.g. onEdit, onOpen), can not access anything that requires the user account or is associated with the user, only "generic" methods. For example, UrlFetchApp, open the current spreadsheet, or read ScriptProperties.
So, in thesis, querying a ScriptDb should be possible, since it's a generic call and has nothing to do with the active user, it's analogous to ScriptProperties. I don't see a workaround that would actually let you query the db, but you could use ScriptProperties instead. You can easily save and retrieve any object you would save on ScriptDb by using JSON.stringify and .parse. Of course, I'm not comparing ScriptDb capabilites with ScriptProperties, it's just a workaround.
Anyway, this seems like a good candidate for an enhancement request on our issue tracker.
I'm looking for examples of a pattern where a demon script running within a GoogleAppsForBusiness domain can parse incoming email messages. Some messages will will contain a call to yet a different GAScript that could, for example, change the ACL setting of a specific document.
I'm assuming someone else has already implemented this pattern but not sure how I go about finding examples.
thx
You can find script examples in the Apps Script user guide and tutorials. You may also search for related discussions on the forum. But I don't think there's one that fits you exactly, all code is out there for sure, but not on a single script.
It's possible that someone wrote such script and never published it. Since it's somewhat straightforward to do and everyone's usage is different. For instance, how do you plan on marking your emails (the ones you've already read, executed, etc)? It may be nice to use a gmail filter to help you out, putting the "command" emails in a label right away, and the script just remove the label (and possibly set another one). Point is, see how it can differ a lot.
Also, I think it's easier if you can keep all functions in the same script project. Possibly just on different files. As calling different scripts is way more complicated.
Anyway, he's how I'd start it:
//set a time-driven trigger to run this function on the desired frequency
function monitorEmails() {
var label = GmailApp.getUserLabelByName('command');
var doneLabel = GmailApp.getUserLabelByName('executed');
var cmds = label.getThreads();
var max = Math.min(cmds.length,5);
for( var i = 0; i < max; ++i ) {
var email = cmds[i].getMessages()[0];
var functionName = email.getBody();
//you may need to do extra parsing here, depending on your usage
var ret = undefined;
try {
ret = this[functionName]();
} catch(err) {
ret = err;
}
//replying the function return value to the email
//this may make sense or not
if( ret !== undefined )
email.reply(ret);
cmds[i].removeLabel(label).addLabel(doneLabel);
}
}
ps: I have not tested this code
You can create a google app that will be triggered by an incoming email message sent to a special address for the app. The message is converted to an HTTP POST which your app receives.
More details here:
https://developers.google.com/appengine/docs/python/mail/receivingmail
I havn't tried this myself yet but will be doing so in the next few days.
There are two ways. First you can use Google pub/sub and handle incomming notifications in your AppScrit endpoint. The second is to use the googleapis npm package inside your AppScript code an example here. Hope it helps.
These are the steps:
made a project on https://console.cloud.google.com/cloudpubsub/topicList?project=testmabs thing?
made a pubsub topic
made a subscription to the webhook url
added that url to the sites i own, i guess? I think I had to do DNS things to confirm i own it, and the error was super vague to figure out that was what i had to do, when trying to add the subscription
added permission to the topic for "gmail-api-push#system.gserviceaccount.com" as publisher (I also added ....apps.googleusercontent.com and youtrackapiuser.caps#gmail.com but i dont think I needed them)
created oauth client info and downloaded it in the credentials section of the google console. (oauthtrash.json)
