hedgedoc docker container dies with uncaughtException: Cannot read properties of undefined (reading 'userid')

[moepman]

Description

Sometimes the hedgedoc docker container dies.

Steps to reproduce

I have not been able to reproduce the bug myself, as this never happend when I used the hedgedoc instance.
I hope that the lines indicated in the backtrace are helpful enough.

Expected behaviour

The error not happening and therefore the docker container not dying.

Logs

Your Setup

The hedgedoc instance is running as a Dockerized Setup on Debian 12. See the config section for the docker-compose from my ansible Setup. The container is behind an nginx reverse proxy.
