Apps Script GmailApp archiving not working - google-apps-script

I have a function which I wish to tie to a daily time trigger in Google Apps Script. The function is supposed to take all e-mails in my Inbox marked as read that are older than 14 days and archive them. Here is the code, which I got from here
function batchArchiveA() {
var batchSize = 100 // Process up to 100 threads at once
var threads = GmailApp.search('label:"inbox" is:read older_than:14d -label:"Delete me"');
for (j = 0; j < threads.length; j+=batchSize) {
Logger.log("Thread " + j);
GmailApp.moveThreadsToArchive(threads.slice(j, j+batchSize));
}
}
I have run this function manually to test it out a few times. However, none of the changes seem to be reflected when I open my Inbox in Gmail. I still have 890+ e-mails in my inbox dating back to 2012 (plus more under the Promotion, Update etc. sub-labels)
Thing is, the execution output initially reported no errors, and I could see that a lot of threads were being loaded and then dealt with in the loop. However, now when I run the script, there are no threads loaded. The search simply returns an empty array and the function exits.
I'm just curious what I am doing wrong. I've looked at the Google Developers reference for the GmailApp but there's not really much I can go on so far as debugging is concerned. And presumably, since the search no longer returns anything, the previous runs actually did work... since if they did archive all the threads older than 14 then the search would indeed no longer find them.
Any ideas why I'm not seeing the e-mails gone from my inbox when I load up Gmail?

Okay, so it turns out it was working, but my inbox was just so clogged up that the search I believe only grabbed a maximum number of threads (which must be something like 400-500) at a time, so I didn't really notice a difference.
I set it in a loop that keeps running as long as search returns an array bigger than 0. Meaning it will run through all threads it can (or, as at the moment, until the maximum execution time limit is hit!). I set the functions to run on a regular basis and my inbox has already shrunk to almost nothing!

Googlesheets check if last execution failed

I have a google sheet with a trigger that kicks off some code at 2 am each night.
sometimes the code fails due to various reason like network issue, or timing out because the site is busy and responses are slow (make numerous api calls)
I was thinking of putting in a code than runs based on a trigger every 15 minutes, to see if the last execution failed, then run my code again.
Been googling and search stackoverflow, but can't find a starting point on how to achieve this.
Basically I want to know if the last execution (which I can see manually in the executions screen) has a failed or time-out status, if it does I'll kick off my code again.
Use exponential backoff. You may want to try the exponentialBackoff_() function, like this:
function myFunctionThatRunsOnATrigger() {
exponentialBackoff_(myFunctionThatSometimesFails);
}
function myFunctionThatSometimesFails() {
//...
}

Read/Write from Sheets is suddenly incredibly slow

I have a large script project that I've been working on for a couple of years that our company is using to track production in a manufacturing environment. Typically, the doGet function that loads the web interface for the tracking tool will execute in 5-15 seconds and is very snappy and responsive. However, since yesterday morning that function is taking 60-90 seconds per execution, and occasionally the web app doesn't open at all (even though I don't get a failure in the log for the doGet function). I've been out of vacation since last week and I'm the only developer with access to the code, so nothing in the code base has changed, and the underlying data in a Google sheet doesn't seem to have had any major shifts either.
I've narrowed things down to see that the reads/writes from/to Google Sheets is the main source of the slow down. I'm reading the data in a batch with getValues(), but a single call to that function on the ~850 rows x 9 columns is now taking almost 20 seconds, where the doGet function (which includes 3-4 getValues calls) ran in less than that as of a few days ago.
I'm completely at a loss for how to debug this issue. Here are a few lines of code from the beginning of my doGet function if it helps. There is more to the function than this, but I can look at the time stamps on the Logger statements to tell that this getValues is running way too slow.
var ss = SpreadsheetApp.openById("SPREADSHEETIDHERE");
var pst = ss.getSheetByName("Panel Status Tracker");
Logger.log("Start Panel Data Get")
var panelData = pst.getRange(9, 1, pst.getLastRow()-8, 8).getValues();
Logger.log("End Panel Data Get")
TIA!
These symptoms would usually suggest that the number of rows in the sheet has increased. Remove any unneeded blank rows at the bottom of the sheet and see if that helps.
If blank rows keep reappearing, chances are that you have a erroneous array formula somewhere in the sheet that causes runaway expansion.
Try adding console.time('sec1') and console.timeEnd('sec1') at various sections of your code to figure out which section takes the most time. If you figure out the section of code, try figuring out the exact line by adding subsections within that section.
console.time()

Service invoked too many times for one day: urlfetch

I am getting the following error in my Sheets Add-on:
Service invoked too many times for one day: urlfetch
I'm aware of the limits here, but how can I tell if I am hitting the "URLFetch calls" of 100,000 or the "URLFetch data received" of 100mB? They are two very different issues and if I'm hitting the first one, I must be making requests unintentionally somewhere because there's no way I'm intentionally making the call 100k times a day. It is possible I'm hitting the 100mb, but the way the error is phrased makes me think I'm hitting the first, is there anyway to know for sure which one I'm hitting?
I have run into that too. I only have 1000 rows going out to a web service. Data did not change neither in my sheet nor in the service. But at some point today most of my cells show #Error with this cause.
I feel like it's going out to re-fetch the results way too often. Is there not some caching that can be employed?
UPDATE (long time due): adding cache was exactly what was needed. So I implemented a function fetch(url) which uses a cache and that way avoids the replicate calls.
function fetch(url) {
var cache = CacheService.getScriptCache();
var result = cache.get(url);
if(!result) {
var response = UrlFetchApp.fetch(url);
result = response.getContentText();
cache.put(url, result, 21600);
}
return result;
}
You currently can not do it.
Perhaps run a counter in your script.

New Google Sheets custom functions sometimes display "Loading..." indefinitely

SPECIFIC FOR: "NEW" google sheets only.
This is a known issue as highlighted by google in the new sheets.
Issues: If you write complex* custom functions in google-apps-script for google sheets, you will occasionally run into cells which display a red error box around the cell with the text "Loading..."
Google has suggested:
If this occurs, try reloading the page or renaming the function and changing all references to the new name.
However for other developers experiencing this issue (and who are unable to escape the "loading..." error), I've written my findings in the answer below on how to get past this (with limitations) consistently.
*We're treating this question as the canonical answer for Google Sheet's indefinite "Error... Loading data" problem. It's not limited to complex or slow functions.
Important Tip: Create multiple copies of your entire spreadsheet as you experiment. I have had 3 google spreadsheets corrupted and rendered completely in-accessible (stuck in a refresh loop). This has happened when I was experimenting with custom functions so YOU HAVE BEEN WARNED!
You will want to try one or many of the following ways to fix this issue:
As suggested by google, try re-loading the spreadsheet or re-naming the function or changing the parameters in the cell to see if this fixes the issue.
Surround ALL your custom functions in a try-catch block. This will help detect code issues you may not have tested properly. Eg:
try{
//methods
}catch(ex){
return "Exception:"+ex;
}
Revert to the old sheets and test your functions and check for any other type of error such as an infinite loop or invalid data format. If the function does not work in the old sheets, it will not work in the new sheets and it will be more difficult to debug.
Ensure NONE of your parameters refer to, can expect to or will ever contain a number larger than 1 million (1000000). No idea why but using a number larger than a million as any parameter will cause your function to fail to execute. If you have to, ask the input to be reduced in size (maybe divide by 1000 or ask for M instead of mm).
Check for numeric or floating point issues where numbers may exceed a normal set of significant figures. The new sheets seems to be a little glitchy with numbers so if you are expecting very large or very complex numbers, your functions may not work.
Finally, if none of the above work, switch to the old google sheets and continue working.
If you find any other limitations or causes for functions to fail to execute, please write them below for me and other users who are heavy g-sheet users!
I also had the infinite loading issue with the following function.
// check if an item can be checked off
function checkedOff( need, have ) {
var retStr = "nope";
if( have >= need ){
retStr = "yep";
}
return retStr;
};
Turns out you shouldn't have a trailing ";". Removing the semicolon solved the problem.
// check if an item can be checked off
function checkedOff( need, have ) {
var retStr = "nope";
if( have >= need ){
retStr = "yep";
}
return retStr;
}
This runs as one would expect.
FWIW, I just ran into this and the culprit ended up being a getRange() call that pulled several thousand rows into an array. Periodically it would get hung on the "Loading..." message.
I worked around it by putting that range into the document cache. It's a little kludgy because the cache only stores strings, not arrays, but you can force it back into an array using .split(',') when you need to access the array.
(In my case it's a single array. There's probably a way to do it using a double array, either by sending each row or column into its own cache, or reading the cache value back N items at a time, each N becoming its own array.)
Here's the relevant bit from my code:
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("mySheet"); //search the "mySheet" sheet
// is the big list already in the cache?
var cache = CacheService.getDocumentCache();
var cached = cache.get("columnValues");
if (cached != null) {
var columnValues = cached.split(','); // take the cached string and make it an array
} else { // it's not in the cache, so put it there
var column = 1; // the column with your index
var columnValues = sheet.getRange(2, column, sheet.getLastRow()).getValues(); // first row is header
cache.put("columnValues",columnValues,60000); // this forces the array into a string as if you used .join() on it
}
This is definitely a bug in Apps Script -- getRange() shouldn't hang without a timeout or error message. But at least there's a workaround. Here's the bug I opened against it, where I've also put the full code.gs from my sheet.
One cause: Permissions needing authorizing.
As far as {this problem, better phrased the cell result(s) of a custom function displaying the disgustingly-vague message ‘Loading... Error: loading data...’}, indeed in the case where all instances of the same/similar custom function call displaying this error, is that Google Sheets needs permissions to run the script (often additionally: meaning in the past it didn't need these), so instead of {acting appropriately: then prompting the user for these permissions else returning that error}, Sheets instead hangs with this disgustingly vague error.
Additional permissions can be needed from 1 or more:
Google App Scripts has since rewriting their permission structure --how this problem now just happened to me, per my internal note O80U3Z.
Your code or some library it uses made changes to require more access ...but in this case you have a much better chance of guessing the cause of this disgustingly-vague error, so hopefully won't be reading here.
To fix, I explicitly ran my GAS spreadsheet code by both: clicking one of my custom menu functions and, in the ‘script editor’, running one of my custom JS functions notably the ‘onOpen()’ since that is most comprehensive. The first promoted me for indeed new permissions, via popup ‘Authorization RequiredThe application "MM6ZBT(MM6Z83 script)" needs authorization to run.’, though onOpen() also did this in cases of GAS revising its permissions since we used that sheet. Then, as I was still getting this ‘Loading...’ error, I reloaded the web page (so the sheet), and, at least for these cases of this disgustingly vague error, it was gone and the computations worked fine :-)
TL;DR - Try duplicating the sheet tab and delete the old one
I struggled with this issue today, and tried some of the approaches mentioned. For various reasons, renaming the function wasn't possible for me.
It was very clear that if I called a my function like this in cell X25:
=myFunction("a", 1, "b", 2, "c", 3)
The cell would be stuck "Loading...", while just changing a parameter slightly (e.g. converting a number to a string) the cell would evaluate fine.
=myFunction("a", "" & 1, "b", 2, "c", 3)
Just copying the code into another cell (e.g. X24) and executing it there seemed to bypass the problem. As soon as I moved it back to the original parameters or cell, it got stuck "Loading..." again.
So I would assume it's some kind of caching of "Cell ID", function and parameters that go bonkers on Google's side.
My good-enough solution was to simply duplicate the Sheet tab, delete the old one, and finally rename the new one back to the original name. This solved the problem for me.
I also had the "loading data..." error but none of the fixes described here worked for me. It didn't seem to be caused by the issues described here. In my case, I narrowed it down to a specific floating point operation issue (it looks like a real bug in Google Sheets to me), and documented one possible work around at
Google Sheets / Apps "Loading data" error: is there a better workaround?
To summarize (at the request of commenter Steve), if a cell with
= myfunction(B10)
generated a "loading data" error, then for me it could be fixed by wrapping the argument in a "value()" function:
= myfunction(value(B10))
which converts the number in cell B10 (which seemed like a normal number but generated problems somehow) into a normal number that works fine.
I also had the problem that you explained. It seems that it can be caused in more than one way.
I ended up finding that my custom function was displaying that error because it relied on data from an =IMPORTRANGE() call, and that call was failing.
I eventually found that the =IMPORTRANGE() call was failing because I had forgotten to update the URL that it was importing from when I had uploaded a new version of that imported-from sheet. It seems that trying to IMPORTRANGE from a trashed file can cause the infinite "Loading..." error.
Update 2022
It looks like this bug is still happening. I tried ALL the solutions mentioned here but none worked.
What worked was to start with a blank slate. I recreated the file, copy-pasted my data, reapplied my preferred style and format, and lo-and-behold the sheet finally managed to pull the data using my custom functions.
This is a definitely a bug on Google's end - and it's all the more annoying because they removed the "Report a problem" button from the "Help" section.
Nevermind
The newer sheet has stopped working too. This is so annoying ..
The problem is that when a custom function formula cell starts showing Loading..., the custom function does not get called at all. The code in the script project thus does not come into play. Even the simplest custom functions sometimes suffer from the issue.
The problem usually goes away if you clear the formula cell and undo, or slightly edit the custom function's parameters to cause it to get re-evaluated. But that does not solve the issue. Google has been dragging their feet solving the underlying cause for many years.

Add-ons
I had two add-ons, and no function was loading.
I removed them, and all is well!
For me, renaming the custom function solved the problem. For now at least.
Just to add to Azmo 's answer...
I in fact removed all trailing semi-colons from the code:
// check if an item can be checked off
function checkedOff( need, have ) {
var retStr = "nope"
if( have >= need ){
retStr = "yep"
}
return retStr
}
And discovered, that when doing this over a large range you can also max out the acceptable number of calls to the API.
To get around it I added an IF THEN check around my custom script call.
So instead of:
=checkedOff(H10,H11)
Use something like this to check for a populated field before execution:
=if(H17<>"-",checkedOff(H10,H11),0)
My app script pulling data from my MSSQL database displayed just fine on GoogleSheets my laptop browser but then did not display on the Android GS app.
Per this thread it looks like there's a number of issues that could cause this, but #DestinyArchitect's answer above re: Permissions seemed like the simplest fix.
While testing my app script, Sharing was off for this GoogleSheet file.
Once I moved it to my team's folder where we have default Sharing switched on with a few team members, the MSSQL data showed right up on the GoogleSheet in my Android GS app.
Easy fix, this time...
In my case, the cell was stuck with a Loading... message due to "probably" a race condition between functions and formulas resolutions.
This is my custom function:
function ifBlank(value1, value2) {
return !!value1 ? value1 : value2;
}
This is the formula calling it:
=IFBLANK(VLOOKUP($A2,Overrides!$A$2:$E,5,FALSE),VLOOKUP($A2,'_resourceReq'!$A$2:$C,3))
Those VLOOKUP values could be pretty complex and could also take some time to resolve.
Solution: (in my case)
Wrapping the VLOOKUP() into TO_TEXT() or VALUE() for example.
So, changing the formula to =IFBLANK(TO_TEXT(VLOOKUP($A2,Overrides!$A$2:$E,5,FALSE)),TO_TEXT(VLOOKUP($A2,'_resourceReq'!$A$2:$C,3))) worked well.
If that doesn't work maybe try resolving the value from a function into a cell before using it as the argument of your custom function.
In my case, multiple cells using functions experienced this issue, but the simple answer was... wait.
In my case, I was scraping data via importXML functions across multiple rows and
columns. I was thrilled with the results, feeling on top of the world, then "Loading..." started showing its ugly face. For way too long. That's how I wound up here in troubleshooting mode, impatient and upset that Google was doing me wrong.
I tried many of the solutions here, only to find my "Loading..." antagonist acting unpredictably, popping up randomly like whacamoles, nothing to do with the code itself.
So. In my case, it was a matter of waiting it out (towards an hour for some rows, but I had so many cells fetching url data).
My layman's guess is that fetching data like this gets put in their bandwidth pipeline, lesser priority than typing a url into a search bar or other user requests.

script exceeding driveWriteVolume rateMax

I have a piece of code that is supposed to create a folder for each email message in a thread, and save the body (as a pdf) and all the attachments (as whatever they are) into that folder.
If I run it without the loop for saving the attachments, I have no problem. (Well, I have a different problem for a different thread). If I uncomment the attachments loop, I get
Service invoked too many times in a short time: driveWriteVolume rateMax. Try Utilities.sleep(1000) between calls. (line 156, file "Code")
All lines that create a folder or a file are followed by a Utilities.sleep(sleepTime); and sleeptime is currently set to 1000. Changing it doesn't seem to have any effect.
The offending piece of code is:
// Save attachments
for(var i = 0; i < messageAttachments.length; i++) {
var attachmentBlob = messageAttachments[i].copyBlob();
newFolder.createFile(attachmentBlob);
Utilities.sleep(sleepTime); // wait after creating something on the drive.
} // each attachment
it is the newFolder.createFile(attachmentBlob); line that triggers the error.
I have looked at What is driveWriteVolume rateMax? and Intermittant DriveWriteVolume rateMax exception for help, and have found none.
Note that if I comment out the loop for attachments, and just save the messages bodies as PDF, I have no problem, regardless of the number of emails I'm saving. When I get the error, the script has died right where it should have saved the first attachment. So I'm thinking there is something else wrong than exceeding some sort of limit.
Your hitting a rate limit. Google api probably has a limit of approx 20 writes / minute, so you'll need to slow your script down in order to avoid triggering the rate limit. In What is driveWriteVolume rateMax? the user in the similar thread used a time of 3000 ms to solve the problem rather than the suggested 1000 ms.
