invalid skaffold config: proxy: unknown scheme: http

[Vertexwahn]

I followed the getting started guide (using skaffold v2.10.0), i.e.:

git clone https://github.com/GoogleContainerTools/skaffold
cd skaffold/examples/buildpacks-node-tutorial
skaffold init
minikube start --profile custom
skaffold config set --global local-cluster true
eval $(minikube -p custom docker-env)

Once I call skaffold dev I get:

invalid skaffold config: proxy: unknown scheme: http

I am behind a corporate proxy.

If I do

unset ALL_PROXY
unset all_proxy

the issue is gone.

Would be nice if skaffold (or its transitive dependencies) would be less pedantic here.
