How make automation jira rule that will assign issue back to developer who created PR on issue

[wojciech.stepien1]

So I would need help to create a rule that will assign issue back to the developer who created PR within that issue when status of the issue is changed from IN TESTING to REOPEN.

Most of advices are pretty old and formulas are no longer valid for me unfortunately

In Jira Automation, you can access the user who created an issue using the smart value {{creator.displayName}} or {{creator}}.   You can create an automation that runs on status change and then assigns it to the creator.
