BUG with kubectl v1.10.0

[pixie79]

It appears the latest version of kubectl is not compatible with v1.9.6

Marks-MacBook-Pro:prest molliver$ kd --config /Users/molliver/git/borders/platform/kube-secrets/dev.env -f ./network-policy.yaml

Yet when I switch just kubectl back to the earlier 1.9.6 version kd works fine.

Maybe overkill but I recommend moving from kubectl to kube client library and making calls as such (e.g.): https://github.com/arehmandev/kubernetes/blob/997861d86635c8c9517ee290f1d79ebb85da155d/staging/src/k8s.io/client-go/examples/out-of-cluster-client-configuration/main.go

But in the short term you could add a kubectl version check.
