A prototype was created successfully using Firebase Studio, tested with email/password was successfully added into Authentication and Firestore users collection.
But when trying to add Google Sign-In, first got “Firebase: Error (auth/unauthorized-domain)”, found the connection was not established to Firebase Console.
Created the project manually in Firebase Console and added .env.local with Firebase configuration, restarted the server.
Then added https://6000-firebase-studio-1748093797246.cluster-6dx7corvpngoivimwvvljgokdw.cloudworkstations.dev as URI in GCP OAuth Client
Google Sign-In popup seems working but closed with error Google Sign-up Cancelled or Failed as screenshot below.
Any suggestion where to look into…
Thanks
