I've created a filter for my Kanban board which works to get all stories from Epics labeled with a specific label:
project = ABC AND issueFunction in issuesInEpics("labels = XYZ")But when I try to base swimlanes on Epics I get an empty board with "No issues are currently visible Check the board configuration" or even when I look for epics in the backlog it is completely empty.
The stories and issues do of course have epics assigned and if I do a simpler query Jira is able to see the Epics. I've got no add-ons nor any sub-filters on the board.
I assume it must be the query but I've no idea what is wrong with it as it works in the search
