I've deployed an angular project on app engine. The website is working fine, except for one issue. I use Google Authentication on this project When developping, I added loaclhost/4200 to my URI whitelist and it worked fine. but now it doesn't anymore.
After deploying, I copied the URL and added it to the whitelist URI of new credentials (as simply adding it to existing credentials didn't work, even after a day of waiting for everything to refresh). My URL looks like that: https://project-name.appspot.com/, I guess it's that one I need to had to my URI whitelist (as the error suggest and as I've done before), but I'm starting to doubt it...
Edit: It seems like the client ID provided in the error message doesn't match any of the credentials on my Google Cloud Platform project. Whitelisting the URL won't change anything, as the I'm not the owner of these credentials and I don't know where it comes from. The full error is the following:
"Not a valid origin for the client: https://myproject.appspot.com has not been whitelisted for client ID 88179289847-3n5tn140jhesoq82bcl8rdj32g6c3sms.apps.googleusercontent.com. Please go to https://console.developers.google.com/ and whitelist this origin for your project's client ID." It's an error 401.
