如何处理Unity上的Firebase身份验证错误

Firebase.Auth.FirebaseAuth auth;
IAuthCredential credential;

// Initialize Firebase Auth.
auth = Firebase.Auth.FirebaseAuth.DefaultInstance;

// Sign in with email and password.
credential = EmailAuthProvider.GetCredential("user@example.com", "password123");
auth.SignInWithEmailAndPassword(credential).ContinueWith(task => {
  if (task.IsCanceled) {
    Debug.LogError("SignInWithEmailAndPassword was canceled.");
    return;
  }
  if (task.IsFaulted) {
    Debug.LogError("SignInWithEmailAndPassword encountered an error: " + task.Exception);
    return;
  }

  Firebase.User user = task.Result;
  Debug.Log("User signed in successfully: " + user.DisplayName);
});

auth.SignInWithEmailAndPassword(credential).ContinueWith(task => {
  if (task.IsCanceled) {
    Debug.LogError("SignInWithEmailAndPassword was canceled.");
    return;
  }
  if (task.IsFaulted) {
    Debug.LogError("SignInWithEmailAndPassword encountered an error: " + task.Exception);
    return;
  }

  Firebase.User user = task.Result;
  Debug.Log("User signed in successfully: " + user.DisplayName);
});
