az aks is broken after `az extension update --name aks-preview`

pramodsetlur commented 4 hours ago

Describe the bug

I am trying to enable NodeAutoProvisioning (Karpenter) for AKS using az aks update --resource-group aks-cilium-karpenter --name aks-cilium-karpeter --node-provisioning-mode Auto.

This command required the following preview extensions. After adding and updating the extension, any az aks commands does not work.

➜  ~ az extension add --name aks-preview
az extension update --name aks-preview

Related command

➜  ~ az aks list
➜  ~ az aks update --resource-group aks-cilium-karpenter --name aks-cilium-karpeter --node-provisioning-mode Auto

Errors

The command failed with an unexpected error. Here is the traceback:

Expected behavior

The cluster should be updated with NAP and az aks list should be able to list the cluster as required.

Something that could be related to this issue. I am also unable to ssh into a VM using a bastion host.
