Error 12501 authenticating with google sign-in

Question

I\'m using google sign-in services to authenticate users that use my app. I got it to work when I just requested email information

GoogleSignInOptions gso =          


        

Answer 1

I had this issue when I accidentally used the client ID of the Android app instead of the Webapp as the requestIdToken() parameter.

You should use the Client ID of the Webapp there. By default it is called Web client (auto created by Google Service)
