Edit Access Required? Using FirestoreGoogleAppsScript in a GAS Library.

Minimal Code to Reproduce the Problem

const firestore = FirestoreApp.getFirestore(email, key, projectId);

Explain the Problem in Detail

Hi, this library is great! Thank you for making it! I wrote a bunch of wrapper functions using it and saved the file as a Google Apps Script Library in of itself. I can invoke my library - which invokes FirestoreGoogleAppsScript - from my Owner account with no problem. I’ve given other users View access to my library so that they can invoke its functions on their own. However, when they try to do so, they get an error: SyntaxError: Unexpected token < in JSON at position 0 Looking at the logs in the Executions Dashboard shows a more detailed stack trace:

SyntaxError: Unexpected token < in JSON at position 0
    at method_(Request:49:34)
    at post(Request:95:21)
    at callback(FirestoreRead:115:41)
    at Execute(Query:241:21)

When I grant the user edit access to my library (the one that invokes FirestoreGoogleAppsScript), the error disappears. I was wondering what would cause Edit access to be required. Thanks

So I have my own copy of this library (use Project ID 1yIYw-qTL5UWCYae8_Qe9NAIxbkNrW289HA0kcWFQNTxlb9WDeVfm2Jcq) which I have added some debug statements for you around the problem statement, including a console.log of the actual response text from FireStore that you should check.

Please report back with your findings!

I’m experiencing a very similar error.

SyntaxError: Unexpected token < in JSON at position 0
    at method_(Request:49:34)
    at post(Request:95:21)
    at get accessToken(Auth:28:70)
    at get authToken(Firestore:34:26)
    at updateDocument(Firestore:94:56)

The library seems to work fine on my account, but this error sometimes occurs when other users try my add-on.

I’m pretty confident it’s not an issue with the format of the credentials, but I’ll continue to look into it.
