How do I properly set up the feature that allows selecting some text in Confluence and adding an issue from the popup? When I try to do that, I get the error message above.
I'm trying this as a user that is an admin on both Confluence and JIRA. I'm using JIRA for user management for both sites. If I simply switch to JIRA with that user, I can easily create new issues.
I'm using the Download versions.
