I use the API to set an owner and it works fine however, the documentation states that to remove an owner the owner should be set to zero and the message I get back is user not found

The Zuludesk/Jamf School API docs say setting owner to 0 removes the owner, but newer versions reject 0 as “user not found.” To clear the owner, you should either send "owner":null or omit the owner field entirely in your request, which removes the assignment without trying to resolve an invalid user ID.
