We currently have a Jira Service management project set up that gets emails from another system and it generates issues. Currently every issue is listing the email address we configured on the other system as the reporter. In the description we have the actual customer's email and I am able to pull it from the description and populate it in a custom email field. The problem I am running into is when I try to make an automation rule that will take the email field and put its value in the reporter field. Currently I am getting the error in the audit logs for the automation rule:
(Specify a valid value for reporter (reporter))
Here is how I currently have the automation rule setup:

Any ideas or insight into this would be great. Thanks.
