OAuth2 for Apps Script: Google Apps Script callback is changed dynamically after login

Question

I am using OAuth2 for Apps Script to create and authorize OAuth2 tokens as well as refresh them when they expire. As per their documentation, I am using Redirect URI of below format:

https://script.google.com/macros/d/{SCRIPT ID}/usercallback

It works for most of the case but it fails for only one user and found that the Redirect URI is changed for him after login. For a better explanation, I have renamed the domain name to abc.com

https://script.google.com/macros/abc.com/d/{SCRIPT ID}/usercallback

I don't understand how it inserts abc.com in the callback. As a result, I am encountering below error:

Library with identifier OAuth2 is missing (perhaps it was deleted, or you don't have read access?)

Any help or suggestion would be great.

Thanks.

Copy paste the oauth script directly instead of using the library and see what new error you get — TheMaster, Aug 31 '20 at 08:50
@TheMaster, your suggestion worked and the error went away. Thanks for your help. But can you please tell me what could be the issue? — Jayakrishnan, Sep 01 '20 at 16:42
I've compiled a list of causes and closed this as duplicate. — TheMaster, Sep 22 '20 at 03:28

This happens when the authorizing user is logged into a GSuite account associated with the abc.com domain. The web app URL changes but other than that, the functionality is not affected.

but it breaks OAuth2 operation and gives me the error "Library with identifier OAuth2 is missing (perhaps it was deleted, or you don't have read access?)" – Jayakrishnan Aug 31 '20 at 08:41
You have to share the Library with "anyone can access" so users outside your domain can access the library. – Amit Agarwal Aug 31 '20 at 10:23
Can you please guide me on how to do it? – Jayakrishnan Aug 31 '20 at 11:17
Open the library inside Google Script Editor and choose File > Share > Anyone can read. – Amit Agarwal Sep 01 '20 at 07:00
