com.google.firebase.FirebaseException: An internal error has occurred. [ CONFIGURATION_NOT_FOUND ]

Question

Ok so I get the following exception. No idea why it is happening. I have followed the guides how to set up auth for google account. I tried to search the google but no success of any solution for this. I haved tried to search for the CONFIGURATION_NOT_FOUND but I could not find it in the firebase docs. I don't know what configuration he can't find. Exception is basically useless. Signing in trough firebase is going great until authenticating it with firebase:

private void authenticateGoogleAccount(GoogleSignInAccount account) {
    AuthCredential credential = GoogleAuthProvider.getCredential(account.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (!task.isSuccessful()) {
                        Log.w(TAG, "signInWithCredential", task.getException());
                        Toast.makeText(MainActivity.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                    }
                    else {
                        Log.d(TAG, "signInWithCredential");
                    }
                }
            });
}

Answer 1

Have you checked the project_id in your Android app google-services.json file is the same as the Firebase project for which you enabled Google Sign In Authentication? If that is the case and you have not edited the google-services.json file, you can file a support ticket to Firebase.

Wow. This is a great answer. I had a different ID than project ID in console. Hope it will work now. Will update – Malik

Thank you. I have re-downloaded the play-services.json and it worked. Finally! – Malik

Answer 2

Check if you enabled the authentication type you want in the firebase console.

Youngyoungblood

I was using signInWithCustomToken(), and just visiting the authentication page in firebase console and pressing on "Get Started" button was sufficient for me. – Bakken

@LahiruChandima - nice! – Passenger

Same. There's goes 2 hours of my day 🙄 – Barnum

No mention of this in the google docs. Thanks google! – Downwind

Yup, get back to the Firebase console, hit Get Started and you're off to the races. Happy dev. – Periphery

Answer 3

Enabling Sign-in method (email/password in my case) in Firebase project dashboard fixed the issue for me.

Answer 4

This error appears if you have not clicked through the interstitial hero in the admin UI. Simply go to the "Authentication" tab of your project and click "Get Started". If you are using custom authentication, no further configuration is required; Google simply fails to properly initialize your project at first.

(Thanks to @Lahiru Chandima for the pointer.)

Answer 5

just head to your project settings in firebase and enable email/password auth

Answer 6

This happened to me in an Android emulator on my Mac M1 developing an app in Flutter, what happened was that the date and time on my Android Emulator was completely out. A cold boot reset the date and time and the Firebase exception issue was solved.

I have same issue and cold boot on M1 android is working! thanks a lot. – Frulla

well you just saved me a few hours of pulling my hair out. Cheers! – Mossberg

Answer 7

If your Firebase one project contail multiple application then download google-service.json file from app->setting->google-service.json and then add in your android studio project.

Answer 8

some people have like google-services (4).json in their project. rename the file to google-services.json and you will be fine

Answer 9

I was having the same issue with my MacBook with M1 chip my emulator date and time were not correct. Setting up them manually saved my day.

Answer 10

for my case, check the appIdSuffix. is the suffix already on Apps in firebase /settings/general page? the google-services.json should contain it suffix

additional: if you already have existing build(app/build folder and so on), remove it first

Answer 11

Please check in /android/build.gradle:

buildscript {
  dependencies {
    // ... other dependencies
    classpath 'com.google.gms:google-services:4.3.14'
  }
}

if the version of google-services is the newest or not (visit https://rnfirebase.io/ to see the newest version if you use that library). Update google-services to the newest that solve my problem.

Answer 12

Make sure you run the flutterfire configure command and follow the instructions

Answer 13

Might sound obvious but make sure your firebase SDK config that you set up in your app points to the correct project.

Firebase config SDK can be found at:

1. Login to your firebase console on the browser
2. Select project
3. Gear --> project setting
4. Scroll to SDK setup and configuration

Example of firabaseConfig:

const firebaseConfig = {
  apiKey: "make sure it points to the correct project",
  authDomain: "PROJECT_ID.firebaseapp.com",
  projectId: "PROJECT_ID",
  storageBucket: "PROJECT_ID.firebasestorage.app",
  messagingSenderId: "whatever",
  appId: "whatever"
};
