~Hello All, We are facing issue in Downstream cluster when we update Rancher. Our setup is: Rancher Version: 2.6.3 Local cluster: K3s 1.23.9 Downstream cluster (on bare-metal) using RKE: K8s 1.21.6 When we are trying to update Rancher from version 2.6.3 to 2.6.6, Cluster agent pod in Downstream cluster (cattle-cluster-agent) is going into crashloopbackoff status. And we see below erros in cattle-cluster-agent pod: starting /v1, Kind=Secret controller" E0804 09:55:45.612622 39 runtime.go:78] Observed a panic: "invalid memory address or nil pointer dereference"
