Is there a possibility to unset the assignee field when showing a transition screen?
Unassigned issues are not allowed in our JIRA instance.
Use case:
When requesting feedback I often forget to also set the new assignee, which requires another edit of the issue and so another email. This is annoying so I want to force me and all other users to choose the assignee. Setting the assignee element to an invalid state would solve the issue.
Post-transition is AFAIK no solution.
