S-JQL for development[pullrequests].open > 0

[Tilman Ulshoefer]

Dear community,

I want to create a workflow validator checking that an issue can only be transitioned to “Done” when all associated pull requests are done as well (from GitHub).

The Structure works fine: project = abc AND statusCategory = Done AND development[pullrequests].open > 0.

However, I fail with the S-JQL formula. Does anyone have an idea how the formula need to look like?

Thank you in advance, Tilman
