@dcole-gsn I found this stackoverflow question about this error

Short answer:

Just change v1alpha1 to v1beta1:

diff ~/.kube/config-backup ~/.kube/config
691c691
<             apiVersion: client.authentication.k8s.io/v1alpha1
---
>             apiVersion: client.authentication.k8s.io/v1beta1

Hi bolshoytoster, Thanks for the link, I had seen that. Tentatively, it seems the issue for me was related to an outdated aws cli version. I updated aws cli from 1.25.55 to 2.9.12 and that seemed to resolve the issue. From my limited understanding aws cli 1.x should be fine, but updating it resolved the issue. Sorry for wasting peoples time. Kind regards.
