Describe the bug
I'm trying to use dsc cli tool directly to route traffic to my local machine. I provide correct arguments to dsc connect command. However, it ends up with a strange error about my kubeconfig:

An unexpected error occurred: 'Failed to perform action on the cluster using the current kubeconfig. You may need to log in by running a kubectl command.'

I can confirm that I can use any kubectl commands without any problems, but somehow dsc have problems with an access to cluster.

Mention the platform you are using
VsCode

To Reproduce
Steps to reproduce the behavior:

  1. Run dsc connect --service my-service-name --namespace=my-namespace --local-port 33001 --use-kubernetes-service-environment-variables --yes -- my command to execute in terminal
  2. See error that looks like this:
An unexpected error occurred: 'Failed to perform action on the cluster using the current kubeconfig. You may need to log in by running a kubectl command.'

Expected behavior
I expect cli tool to connect to cluster and start to forward traffic from specified service to my local machine
