Whenever I try to set the Jira Service Desk automation default user, the list possible users is always blank.
This is on a sandbox test project. I'm set up as site-admin, jira-admin, Admin role and Service Desk Team role on the project, and team lead on the project. The permission scheme has all permissions opened up for all Admin role members, so I should have the required permissions to execute specific rules.
Even with all of this, I can't set up myself, or anybody, as the automation rules default user. It just shows "The selected user has been deleted." and the dropdown of possible users is always empty.
Is there something I'm missing, or is this a bug?
