I was about to merge when I found things were failing when pushing in my fork.

Ginkgo detected a version mismatch between the Ginkgo CLI and the version of Ginkgo imported by your packages:
  Ginkgo CLI Version:
    2.19.1
  Mismatched package versions found:
    2.20.1 used by server
...

It only happens with this job

          - irods: "4.3.1"
            server_image: "ghcr.io/wtsi-npg/ub-22.04-irods-4.3.1:latest"
            experimental: false

I retried a couple of times to see if it was a temporary thing but still failing. Will it be ok if I retry the CI job from the PR to see if it replicates here?
