It seems to have found the kubeconfig:

2020-07-08 22:38:37 INFO __main__ Creating kubernetes client with config /home/dgzlopes/.kube/config (path found for backwards compatibility)

But yeah, we should make the error more pretty.

Yep, we should improve the error.

It can be triggered in some other ways:
