Unable to upgrade connection: Authorization error

[bcf_ant]

I'm getting the following error when I try to exec into a pod.

error: unable to upgrade connection: Authorization error (user=kube-apiserver, verb=create, resource=nodes, subresource=proxy)

Nodes are running an old version that need to be updated (1.16.8-gke.9).

Are your nodes really running 1.16.8?  What is your control plane version?

Can you try running

kubectl auth can-i get pods/exec

I know, terrible 😳 The plan is to switch to an autopilot cluster.

Control plane version 1.22.17-gke.7500

I get a yes when I run the following command. 

---

kubectl auth can-i get pods/exec

I can create pods, destroy them, list pods..

@garisingh any suggestions?
