Fix FirebaseAuthError

✅ Solution

FirebaseAuthError often indicates an issue with the Firebase project configuration or the token itself. Ensure the Firebase project ID and API key in your application match the Firebase project where the token was generated, and that the token hasn't been tampered with. Refresh the Firebase configuration within your application and regenerate a new ID token to rule out cached or corrupted tokens. Lastly, check for clock skew between the client and server by looking at 'iat' and 'exp' fields to ensure validity.
