While investigating the current samples operator install issue, I found a panic in this job: https://prow.ci.openshift.org/view/gs/test-platform-results/logs/periodic-ci-openshift-release-master-ci-4.19-upgrade-from-stable-4.18-e2e-gcp-ovn-upgrade/1900430675614371840

Following is the error message:
