@gshaibi I had the same problem I found that there was mal formed endpoint for one of my services (one that I was not trying to debug).

run kubectl get endpoints to make sure all of your services have an endpoint defined. I had a port missing in the deployment spec of it

[gshaibi]

I'll check it out and update. Thanks @williamohara!

@gshaibi
check this out... #288
this feels like a bug with bridge to kubernetes - they should consider that some services will not have endpoints defined. my solution is more of a workaround.
