Hello everyone,
In all our Service Management projects, there is a small error pop-up in the lower left corner of the screen whenever the incident is opened.
The message appears without context or additional information and disappears on its own after some time.
Since the message appears for all incidents in all projects and I don't receive any further information about the error, I'm at a loss for what else I could investigate to resolve the issue.
Has anyone else experienced this or a similar problem? Are there any ideas from the community?

Edit:
I was able to identify in the page's source code what is causing the error:
{"errorMessages":["Field 'Work category' does not exist."],"warningMessages":[]}
But how can I fix this?
