Nikolai presented a Cloud ScripRunner solution for round-robin assignment during the Zoom meeting this morning, in the ScriptRunner Champion Hour February 2022, and the moderator suggested that listeners post a reminder for Nikolai to publish his script for that in the Community.
So, this will hopefully serve as that reminder. The upshot of the problem was about dealing with the fact that Jira Cloud has easy storage of previous assignees and the importance of collecting user-ids in preparing to make those assignments.
