This problem occurs after update the client-go to " >= v0.27.0".
The type ResourceEventHandlerRegistration is added to client-go from v0.26.0. But it is different with 0.27.0.

0.26.0:
type ResourceEventHandlerRegistration interface{}
0.26.4
type ResourceEventHandlerRegistration interface{}
0.27.0

type ResourceEventHandlerRegistration interface {
	// HasSynced reports if both the parent has synced and all pre-sync
	// events have been delivered.
	HasSynced() [bool](https://pkg.go.dev/builtin#bool)
}

meet the same problem here: openshift/ingress-node-firewall#334

I think you need to update controller-runtime to a version that includes kubernetes-sigs/controller-runtime#2223 before updating to client-go 0.27.0 (which may mean controller-runtime needs to tag a version that includes that)

@liggitt Thank you so much!
