panic: runtime error: invalid memory address or nil pointer dereference

This all worked great on minikube. Moving to a more productionalized cluster it's all falling apart and very difficult to work with.

DiscoverSriovDevices() spits out 2 lines (should be more) then spews this

E0919 13:55:29.535370 1515138 writer.go:78] RunOnce(): first writing to node status failed: unable to update node <nil>: Timed out trying to fetch node knode01.foo.bar.baz.com: sriovnetworknodestates.sriovnetwork.openshift.io "knode01.foo.bar.baz.com" not found

Finally crashing:

It seems like the operator is not able to create the SriovNetworkNodeState for the node knode01.foo.bar.baz.com. Can you provide the operator logs?
