[sahil-lakhwani]

I installed using go install github.com/awslabs/eks-node-viewer/cmd/eks-node-viewer@latest

$ eks-node-viewer                       
2022/12/09 11:43:21 creating client, exec plugin: invalid apiVersion "client.authentication.k8s.io/v1alpha1"

Credentials are correctly configured

In your kubeconfig, what version is set for apiVersion?

- name: arn:aws:eks:us-west-2:12345678:cluster/your-cluster-name
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1beta1

Im getting the same error

- name: dev.cluster.lab
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1alpha1
      args:
      - token
      - -i
      - eks-dev-cluster
      command: aws-iam-authenticator
      env: null
      provideClusterInfo: false

@tzneal The version in my kubeconfig is client.authentication.k8s.io/v1alpha1

[ilyatovbin-pp]

replace all v1alpha1 to v1beta1 in kubeconfig, then make sure your kubectl version supports it. I updated mine from 1.21.x to 1.23.15 and the issue went away.

I added some docs in #18 that should clear this up.
