I'm trying to add Google sign-in in my website, I made an Oauth Client on Google Cloud Platform but I can't add my javascript url as an allowed source.
I'm getting Erreur 400 : redirect_uri_mismatch https://________.script.googleusercontent.com, does not match the ones authorized for the OAuth client. Visit https://console.developers.google.com/apis/credentials/oauthclient/______.apps.googleusercontent.com?project=______ to update the authorized JavaScript origins.
I'm using Apps script to developp it and https://script.google.com doesn't work as an allowed source for the oauth client.
Does someone has a solution ? Is there a way to make it work ?
Edit : my situation is similar to this post : Google Sign in redirect_uri_mismatch, however I can't add any URL looking like this. Google Platform does'nt allow them.
