[Bug] An internal error has occurred on Authentication

[RafaelGomes00]

Description

I use the authentication system on Firebase on my project, and suddendly I started receiving this error:

System.AggregateException: One or more errors occurred. (An internal error has occurred.) ---> Firebase.FirebaseException: An internal error has occurred.
at Firebase.Auth.FirebaseAuth.SignInWithEmailAndPasswordAsync (System.String email, System.String password) [0x00038] in /Users/runner/work/firebase-unity-sdk/firebase-unity-sdk/android_unity/armeabi-v7a/auth/swig/Firebase.Auth_fixed.cs:3840
--- End of inner exception stack trace ---
---> (Inner Exception #0) Firebase.FirebaseException: An internal error has occurred.
at Firebase.Auth.FirebaseAuth.SignInWithEmailAndPasswordAsync (System.String email, System.String password) [0x00038] in /Users/runner/work/firebase-unity-sdk/firebase-unity-sdk/android_unity/armeabi-v7a/auth/swig/Firebase.Auth_fixed.cs:3840 <---

My coworker managed to fix this problem for him just by reinstalling the Firebase SDK, wich did not worked for me.
What I have tried:

• Reinstalling Firebase entirelly on the project;
• Downloading the assets directly from my coworker;

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hey @RafaelGomes00, thanks for reaching out. So far, I've checked our quickstart for Auth and the SignInWithEmailAndPasswordAsync seems to work fine.

Could you double check if you've added the google-services.json? Also could you try using the Asset > External Dependency Manager > Android Resolver > Resolve/Force Resolve and see if that changes anything?

Hello, I double checked it and I have the google-services.json under Assets > Streaming Assets, and also tested outside that scope wich gave me the same error.
Also using Android Resolver > Resolve/Force Resolve dont work either.

I will check using the sample on quickstart for Auth to see if it works

[RafaelGomes00]

I created a new project with only Firebase Auth installed, and used this code to log in:

    [SerializeField] private string email;
    [SerializeField] private string password;

    void Start()
    {
        StartCoroutine(Login(email, password));
    }

    public IEnumerator Login(string email, string password)
    {
        FirebaseAuth auth = FirebaseAuth.DefaultInstance;
        var loginTask = auth.SignInWithEmailAndPasswordAsync(email, password);

        while (!loginTask.IsCompleted)
        {
            yield return null;
        }

        if (loginTask.Exception != null)
        {
            Debug.Log(loginTask.Exception);
        }
        else
        {
            if (!auth.CurrentUser.IsEmailVerified)
            {
                Debug.LogError("User not verified");
                yield break;
            }

            Debug.Log("User logged in");
        }
    }

Wich gave me the same error

Thanks for trying that out. I have a couple more questions, just to make sure we check everything.

Do you have the initialization code for Firebase before calling Auth?

public virtual void Start() {
      Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(task => {
        dependencyStatus = task.Result;
        if (dependencyStatus == Firebase.DependencyStatus.Available) {
          InitializeFirebase();
        } else {
          Debug.LogError(
            "Could not resolve all Firebase dependencies: " + dependencyStatus);
        }
      });
    }

Also is the Sign-in provider for Email/Password enabled?

Do you have firewall enabled? If so, you could try whitelisting these endpoints:

identitytoolkit.googleapis.com
securetoken.googleapis.com

So far, I don't see any service disruption in our status dashboard, so I'm guessing it's not an issue on the backend.
