How to handle Firebase auth errors in Unity

Question

I created a simple password in my Unity application after the doc , and it works fine, however I would like to handle various errors, and since it task.Exceptiondoes not return an error code, I do not know how to do it.

I found this one , but it does not look like the same version of Firebase as the login method is different ...

Firebase has an AuthError rename that tells you the value of each ErrorCode in FirebaseException, the documentation is here: https://firebase.google.com/docs/reference/unity/namespace/firebase/auth p>

To get the error message in Spanish, I do the following:

public static string GetErrorMessage(Exception exception)
{
    Debug.Log(exception.ToString());
    Firebase.FirebaseException firebaseEx = exception as Firebase.FirebaseException;
    if (firebaseEx != null)
    {
        var errorCode = (AuthError)firebaseEx.ErrorCode;
        return GetErrorMessage(errorCode);
    }

    return exception.ToString();
}

private static string GetErrorMessage(AuthError errorCode)
{
    var message = "";
    switch (errorCode)
    {
        case AuthError.AccountExistsWithDifferentCredentials:
            message = "Ya existe la cuenta con credenciales diferentes";
            break;
        case AuthError.MissingPassword:
            message = "Hace falta el Password";
            break;
        case AuthError.WeakPassword:
            message = "El password es debil";
            break;
        case AuthError.WrongPassword:
            message = "El password es Incorrecto";
            break;
        case AuthError.EmailAlreadyInUse:
            message = "Ya existe la cuenta con ese correo electrónico";
            break;
        case AuthError.InvalidEmail:
            message = "Correo electronico invalido";
            break;
        case AuthError.MissingEmail:
            message = "Hace falta el correo electrónico";
            break;
        default:
            message = "Ocurrió un error";
            break;
    }
    return message;
}

I finally found a way to display only error messages using this:

FirebaseException error = task.Exception.InnerExceptions[0] as FirebaseException;
string errorMsg = error.ToString();

However, this does not solve the theoretical problem, since it seems that something is missing in Firebase for Unity (at least for now).

FirebaseAuth.DefaultInstance.CreateUserWithEmailAndPasswordAsync (Email.text, Password.text).
ContinueWith (task => {
        if (task.IsCanceled) 
        {
            Debug.LogError ("CreateUserWithEmailAndPasswordAsync was canceled");
            return;
        }
        if (task.IsFaulted) 
        {
            Debug.LogError ("SignInWithEmailAndPasswordAsync encountered an error: " + task.Exception);
            //      
            ErrorText.text = "Error: " + task.Exception.InnerExceptions[0].Message;
            //
            return;
        }
});
