But I can't reproduce it after several runs on my side.

I reproduce it on my side. It doesn't seem to be relevant to the current pr, because this error also occurs on the master branch. https://github.com/karmada-io/karmada/actions/runs/11851539681/job/33028378247

Yes, It seems not related, but it might be caused by Kubernetes dependencies update, I tracked this on #5796.
