PHP Warning: Undefined array key "[status|responsible]" in AuthenticationService.php

[Moongazer]

Describe the bug
On a freshly installed project setup using https://github.com/Leuchtfeuer/ungeheuer, the backend-login fails with some "Undefined array key" warnings. This happens only if username/password for a BE user is used instead of Auth0-login:
