Additional context
Add any other context about the problem here.

Start by reproducing the email login flow in the Enatega customer application and inspect the login and error-handling entry points. The issue provides no file, test, or reproduction details, so first identify where the null error is generated. Done means a new user can log in by email without the null error appearing.
