I'm trying to create a new issue on a specific transition. One of the parameters is to add a comment to the existing issue that's only visible to the jira-software-users group (this is a custom service desk workflow; we don't want customers to see the comment.)
I keep getting the following error (seen in the transition's post function screen, no error being displayed to me as an end user). "Incorrect request: {"commentLevel":"Group level visibility has been disabled."}
Here's the setup, and the detailed log. Anyone have any ideas what is causing this and how to fix it?
