"Query failed: 'NoneType' object is not iterable" Error when starting Verba Chat

[Badhansen]

Description

Application is up and running, but Verba Chat is not working. It is showing "Something went wrong: 'NoneType' object is not iterable", although Verba variables are available.

If I look at the logs, I see the following:. Included some lines above and below for context.
