Triggering pipelines for Omnibus security merge requests is failing
Today, our tooling attempted to trigger a pipeline for a Omnibus security merge request targeting master
https://ops.gitlab.net/gitlab-org/release/tools/-/jobs/1970457, and it failed with:
Gitlab::Error::BadRequest: Server responded with code 400, message: 'base' Pipeline filtered out by workflow rules.. Request URI: https://gitlab.com/api/v4/projects/15667093/merge_requests/30/pipelines
When implementing Pipelines for merged results it was assumed Omnibus uses similar CI rules as GitLab, but it seems that's not the case.
We need to investigate why it's failing and fix it.
As a workaround, Omnibus has been removed from the security "early-merge" phase - gitlab-org/release-tools!1218 (merged)
