I am building an automation to link issues with the same external ID to across projects in Jira. I tried using the Lookup issues action. I started with

But it fails to find anything. From the Audit Log:

I replaced the {{issue.REDCap ID}} with an actual value, 1102, and still received that "result". The JQL with a set value works when used in Issue Search and it returns one record like it should.

Do I need to use the custom field id number in the automation JQL? Any other ideas why it isn't returning results?
