I have a roadmap based on a simple filter: key in portfolioChildIssuesOf(JIRA-###), where JIRA-### is the parent issue type for epics. I can view the roadmap and make changes in JIRA with no issues, but when I try to link it to confluence using the JIRA roadmap gadget. It gives me the below error:
We can't display this Jira roadmap. It looks like it's missing some required details.
When I create an advanced roadmap using the same exact filter, I'm able to display it in confluence without an issue.
Any idea on what the issue could be?
