Make the Assignee field mandatory whenever a user transitions an issue/ticket into a new workflow status. Currently, users can change the workflow status of an item without assigning an owner. When a user selects or transitions an item to a new workflow status: If Assignee is empty, prevent the status change. -> Prompt the user with a message such as: “Please assign an owner before moving this item to this status.” ->Only allow the transition once an Assignee is selected.
