Manual sidecar injection gives an Error

Hi,

I am trying to manually inject istio sidecar into a deployment according to the instructions here:

I am getting the following error, however:

$ istioctl kube-inject -f k8s/prod/deployment.yaml
Error: missing configuration map key "values" in "istio-sidecar-injector"

This error occurs to me even why I try different kinds with different yaml files. Is this a bug or am I doing something wrong? How can I add “values” to the configuration map?
