Looks like both propose-downstream and pull_from_upstream can create the update merge request in gitlab centos dist-git: https://gitlab.com/CentOS/Integration/packit-cbs/rpms/python-specfile/-/merge_requests.
However the jobs are marked as failed in our dashboard.
Sentry registered this error: PCKT-002-PACKIT-SERVICE-936.
I suspect this is raised when cleaning up the workspace.
Packit failed on creating pull-requests in dist-git (https://gitlab.com/CentOS/Integration/packit-cbs/rpms/python-specfile.git):
You can retrigger the update by adding a comment (/packit propose-downstream) into this issue.
