Checked the testgrid, still could reproduce the error, please see:

https://deck-ci.apps.ci.l2s4.p1.openshiftapps.com/view/gcs/origin-ci-test/logs/release-openshift-ocp-installer-e2e-aws-4.6/124

Comment 5 Maciej Szulik 2020-06-16 08:39:45 UTC

This is one occurrence from the test grid https://testgrid.k8s.io/redhat-openshift-ocp-release-4.6-blocking#release-openshift-ocp-installer-e2e-aws-4.6&sort-by-flakiness=
from Jun 6th where it looks like the code wasn't properly synced, yet. It's impossible for this path to fail at this place given the fix linked in this PR.
I've checked the test grid and with the rate failure of this particular tests there's nothing to be worried about, I've noticed only 2 failures in the 
past 3 weeks. Moving this back for verification.

Maciej Szulik :

Thanks , check the test grid again, no more new failed in the latest few days , will verify it .
