I am a Unity programmer and I am using Firebase to manage user accounts. I tried to set up Facebook Login. No problems with the Facebook sdk and I can log in successfully. However, when the credential returned by Facebook sdk is used as a parameter of FirebaseAuth.DefaultInstance.SignInWithCredentialAsync, it returns internal error.

And here is my code:

void authCallBack(IResult result) {

    if (result.Error != null) {

        Debug.Log(result.Error);

    }

    else {

        if (FB.IsLoggedIn) {

            Debug.Log("Log in successfully.");

            AccessToken token = AccessToken.CurrentAccessToken;

            Credential credential = FacebookAuthProvider.GetCredential(token.TokenString);

            accessToken(credential);

        }

        else

            Debug.Log("not logged in");

    }

}



public void accessToken(Credential firebaseResult) {

    FirebaseAuth auth = FirebaseAuth.DefaultInstance;

    Debug.Log("Auth CurrentUser: " + FirebaseAuth.DefaultInstance.CurrentUser);

    if (!FB.IsLoggedIn){

        return;

    }

    if (auth.CurrentUser != null && !string.IsNullOrEmpty(auth.CurrentUser.UserId)){

        Debug.Log("CurrentUser ID: " + auth.CurrentUser.UserId);

        auth.CurrentUser.LinkAndRetrieveDataWithCredentialAsync(firebaseResult).ContinueWith(task =>

        {

            if (task.IsCanceled || task.IsFaulted)

            {

                Debug.LogError("LinkWithCredentialAsync encountered an error: " + task.Exception);

                // TODO: Show error message to player

                return;

            }



            FirebaseUser newUser = task.Result.User;

            Debug.LogFormat("Credentials successfully linked to Firebase user: {0} ({1})",

                newUser.DisplayName, newUser.UserId);

        });

    } else {

        auth.SignInWithCredentialAsync(firebaseResult).ContinueWith(task =>

        {

            if (task.IsCanceled || task.IsFaulted) {

                Debug.LogError("SignInWithCredentialAsync encountered an error: " + task.Exception.InnerExceptions[0].Message);

                // TODO: Show error message to player

                return;

            }

            FirebaseUser newUser = task.Result;

            Debug.LogFormat("Credentials successfully created Firebase user: {0} ({1})",

                newUser.DisplayName, newUser.UserId);

        });

    }

}

More details in VS Debugging:

When I test it on my Android device, it comes out an error message g_methods_cached only.

Can anyone help?

P.S. Here is another question asked yesterday and I don't know if it is relevant.
FirebaseAuthWebException not found. Please verify the AAR

Oh, I have made a silly mistake!

In the Facebook Developer page, there is the App Secret in Setting > Basic. And it has to be added into Firebase Console with the App ID. No problem right now. And then......

I just copied the App Secret without showing and pasted into Firebase Console.

Which means I have set 8 black dots (●●●●●●●●) as my App Secret in my Firebase Console. I know it is too silly. But just in case there is someone careless like me.
