        Returned if the category does not exist or the client does not have sufficient permissions
        to see it.

        **Required permission:** view project (defining the category)

        *Note: A client without sufficient permissions shall not be able to test for the existence of
        a category. That's why a 404 is returned here, even if a 403 might be more appropriate.*
