@peopleinside Thank you for your help !
how did you installed UVdesk?
Do you installed by SSH or docker?
I can't remember whether I installed uvdesk with the ZIP file or with composer, but I'm sure it wasn't with docker.
Are you running on Apache or Nginx?
My UVdesk installation runs under Apache 2.
As soon you change dev to prod and clear the cache you get the error?
No, I get the error when I try to connect to the help desk part of the application.
Unfortunately I'm not a developer and I'm not part of the UVdesk team.
I'm just trying to help you as the UVdesk team can be busy and not present for some week here on the forum.
I know that the UVdesk team isn't always present on the forum.
