[FR] Better debug message when sign-in method is not enabled from Firebase console

[personalnadir]

I am seeing a consistent errors when trying to create or sign in users in the Unity Editor and on iOS device (Android not attempted yet). Both CreateUserWithEmailAndPasswordAsync and SignInWithEmailAndPasswordAsync throw errors caused by internal errors.

No doubt I am doing something wrong, but I'm struggling to dig out what the underlying issues are.

The bug report as such is that the exceptions should contain more detail of the fault so that developers can fix the issues

It turns out the issue was that e-mail authentication was not enabled on the Firebase console. That sounds daft, but it was not mentioned in the authentication start guide or the documentation:
https://firebase.google.com/docs/auth/unity/start

https://firebase.google.com/docs/reference/unity/class/firebase/auth/firebase-auth#class_firebase_1_1_auth_1_1_firebase_auth_1a0490b9393cdad6ec8632769fcf3254cd

The auth SDK should report if the authentication method has not be switched on in the console, instead of generating an internal error.

Thank you for reporting this. I will change this into a FR for better debugging message. Also modify the title a bit.

TL;DR; When a certain sign-in method was not enabled in Firebase console, instead of throwing an Firebase.FirebaseException: An internal error has occurred, the exception should provide more context for the developer to act upon.

This might need some change in iOS/Android SDK level as well. Need to investigate a bit.
