Performing this example: https://github.com/serverless/serverless-kubeless#try-out-the-example

I get this error. Not sure what the problem is.

Thanks.

I see, the problem is that the library we are using to connect to the K8s cluster still doesn’t support EKS authentication. See: https://github.com/godaddy/kubernetes-client/issues/306 (note that the go library does, that’s why you can still use the kubeless binary).

As suggested in that issue you can try to use a service account token to authenticate instead.

Thanks @andresmgot.

I forgot to note, the examples in the getting started guide work successfully. So I believe it’s specific to the serverless-kubeless plugin.
