"Missing or insufficient permissions" when upgrading above 9.16.0

[MvRemmerden]

After upgrading next-firebase-auth to 1.0.2 and following the new way of initializing the firebase app before NFA, I now get "Missing or insufficient permissions" if I use firebase 9.17.1, but it works as expected when I use 9.16.0.

Did this maybe not get caught in the example app, because there are no security rules?

That's possible. Are you using the default Firebase app? Could you try removing all properties except apiKey from firebaseClientInitConfig in the NFA config, just to make sure NFA is using the same Firebase app that you initialize?

@kmjennison You might be onto something here, when I remove all other properties I'm getting this error:

FirebaseError: Firebase: Firebase App named '[DEFAULT]' already exists with different options or config (app/duplicate-app).
