@csviri you are right, I messed up the key, it "should" be:

github.event.pull_request.head.repo.owner.login

instead of:

github.event.pull_request.repository_owner

Do you mind to check?

Well, it turns out that this "feature" might actually break the Quarkus extension… 😓

Would be nice to set up some sort of CI that would check the quarkus extension for each PR we create it, similarly to what the Quarkus CI does…

NDR: the Quarkus CI uses the "star" ⭐ action as an hook for running external GH actions

Actually, it's not breaking so all good. Setting up CI should still be done.
