Component Readiness detects a regression where installer panic due to invalid memory address or nil pointer dereference.

Component Readiness test details link.

This has affected multiple tests:

"install should succeed: overall"
"operator conditions cluster-autoscaler"
"operator conditions machine-api"
"operator conditions monitoring"
"operator conditions ingress"
