Script Runner for Cloud: Team (Next-Gen) vs. Company Managed Projects

[William Asbill]

When using the following filter* in Script Runner for JIRA Cloud (Company Managed Project), I get the message "Not available with next-gen projects yet!"

* issueFunction in issuesInEpics("key = AB-12345")

But, my understanding is that Next-Gen projects applies to Team Managed Projects, not Company Managed Projects, as I am using.

Do I need to update, adjust a configuration perhaps?
