How do I mention the assignee of the trigger issue in the destination issue comments?

[Dayna Portillo]

I am building an automation where the trigger is "Issue Linked," and the action I want to perform is to comment and mention the trigger issue's assignee on the branched Destination issue (see screen capture for steps).

I've tried every suggestion on these community posts, along with some random ones that I knew wouldn't work but tried anyway.  Nothing has successfully tagged the issue assignee in the comments -- results are either blank or "@unknown."  Is anyone else experiencing this, or can possibly explain why these methods are not working?  does anyone know of an alternative method?  

Thanks in advance for any insight!

Hello @Dayna Portillo 

Welcome to the Atlassian community.

This works in my instance:

[~accountid:{{triggerIssue.assignee.accountId}}]

The closest you have is this, but there is a space after the colon.
