Flutter: FirebaseException: An internal error has occurred. [ CONFIGURATION_NOT_FOUND ]

Question

I was able to do google sigin successfully, when I pass token to firebase it returns :

W/System  (20511): Ignoring header X-Firebase-Locale because its value was null.
I/flutter (20511): [firebase_auth/unknown] com.google.firebase.FirebaseException: An internal error has occurred. [ CONFIGURATION_NOT_FOUND ]

My json file is quite good. I implement :

final _auth = FirebaseAuth.instance;
  String email;
  String password;

RoundButton(
                title: 'register',
                color: Colors.blueAccent,
                onPressed: () async {
                  try {
                    final newUser = await _auth.createUserWithEmailAndPassword(
                        email: email, password: password);
                    if (newUser != null) {
                      Navigator.pushNamed(context, ChatScreen.id);
                    }
                  } catch (e) {
                    print(e);
                  }
                })

Have you enabled `Email/Password` in firebase>authentication>sign-in method? — Jake, Jan 03 '21 at 23:35

This can be caused by a disabled Email/Password sign in, which is disabled by default. Enable on the Authentication section in firebase console as shown below.

This works for me. You have to enable the auth method first before you can use it. – Gengjun Wu Jun 20 '22 at 11:12

My solution was different because I had to change the Firebase project I was using and therefore swap out the google-services.json file in my project.

I realized it kept trying to communicate with the old Firebase project so I had to delete app/build and run the project again. I restarted VSCode too, but I don't know if that is necessary.

Hope this helps anyone else that was in my situation.

because sign-in Authentication using [email-password] is disabled by default so go to flutter console ==> Authentication(https://console.firebase.google.com/project/chat-app-c29e1/authentication/users) ==> Native providers ==> cilck on email/password (enable it) then rerun your flutter project
