I was able to find a useful article on how to set up post-functions for Jira server, however, the document states this does not apply to Jira Cloud. Never the less, I attempted to add the post-functions, but they did not work.
I am trying to set it up for custom fields, where for example, when the user transitions to 'In Progress' it auto stamps them to a custom 'Engineer' field using the '%%CURRENT_USER%%' functionality.
We had this set up at my previous company and I cannot seem to get it to work now. Any tips?
