And this only happens when moving tasks? everyhting else works fine?=

[cheetah747]

Yes, this 500 error currently seems to only occur when dragging a task.

There is also a 401 error.After I drag a task (regardless of whether an error occurs or not) and then log out, the following 401 error is reported. However, if I log out without dragging any tasks after logging in, this does not happen. Everything else is currently working fine.

I have the same issue when dragging tasks in the list view (500 + disk I/O error: permission denied in the logs).

Additionally, I have a similar issue when creating a New Saved Filter. The web app says: "Internal Server Error" and the logs say: level=ERROR component=http method=PUT uri=/api/v1/filters status=500 latency=50.03006ms err="disk I/O error: permission denied.
Other write operations are possible, so it doesn't seem to be a general problem with the environment config.

I am using vikunja:2.1.0. I can't reproduce it on try.
