Roadmap not available despite board filtering issues only from 1 project (and 1 epic)

Question

I wanted to enable roadmap for our side project but was getting error:

Your roadmap isn't available because the kanban board filter contains multiple projects. To use your roadmap, adjust the board filter to include issues from Project name only.

The issue is that actually board filter is including issues only from a single project (but also limits them to only a single epic). As in such case kanban board is NOT displaying subtasks by default, we have and additional condition that also displays sub-tasks for all tasks in this single Epic that we are using. Our query:

project = OP AND ("Epic Link" = OP-127) OR (issuetype = Sub-task AND parentEpic in (OP-127)) ORDER BY Rank ASC

Why jira roadmap is still saying that we have to limit issues to only 1 project (which has been already done, project key 'OP').

Hi Adam - Welcome to the Atlassian Community!

Yes, Roadmaps are valid for only one project. If you need multiple projects in a single roadmap, you will need to upgrade your Jira subscription to Premium and use the Advanced Roadmaps.

It could be that the second query does not contain project.

Try adding it and see if it likes it better then.

Jira Roadmap only supporting one project makes no sense since it is tied to a board, that has never been one project only, but just is a visual representation of a filter.
