Same thing is happening to me i think i tried to deploy on unraid and kept getting errors i spend hours trying to fix it. static codes seem to work but dynamic wont generate and save the image.

Hi, I ran into this issue due to deleting the original super admin account that is created with the setup. This then throws an error dus to the dummy data still linked to that user Id, the user no longer exists and a header redirect is put for then the user is not found. This is a case of reusing a find user function that also redirects to block the user from doing something.

The qouch fix for anyone running into this is to delete the dummy data from the database tables.
