If openshift-config-managed/router-certs secret does not contain any certs, the auth operator logs will be filled with the following errors: E0909 19:49:58.876033 1 base_controller.go:180] "ConfigObserver" controller failed to sync "key", err: .servingInfo.namedCertificates accessor error: <nil> is of the type <nil>, expected []interface{} While an empty router-certs secret is an anomalous condition, this error being logged by the auth operator complicates someone trying to troubleshoot the issue, as per [1]. 1: https://bugzilla.redhat.com/show_bug.cgi?id=1876919
QA: The fix has already merged (back in June). One possible strategy to verify is to disable the ingress operator and manually remove the data from the openshift-config-managed/router-certs secret and ensure that the mentioned error message does not appear in the logs. Once you're comfortable marking this bz as verified I will be able to merge the 4.5 backport.
