Still trying to understand what is going on. I was able to find where it updates the status with

atlantis/plan

. Its putting it on the

refs/merge-requests/19/merge

branch instead of the source commit branch or the merge request.

Hmm, seems like the behavior changes with this merge request https://github.com/runatlantis/atlantis/pull/3887. Previously refTarget would be

refs/merge-requests/19/head

, now i’m seeing refTarget

refs/merge-requests/19/merge

.

It has to do with the merge option

Enable merged results pipelines

. Disabling it, adds the external stage with the atlantis/plan. (I’ll revisit this.) The atlantis/apply job is missing though, so i’m able to merge without atlantis applying.
