unable to create API : upstream_url error

[mpgtek]

First of al,l great job on the admin tool! I have it running on my windows 7 box for testing(the instructions are great). My Kong server is running on Linux. When I try to create a new API I get the following error:

Name: "Test Api" request host: "www.mydomain.com" request path: "/api/test" Upstream Url: "testapi"

The response : {"upstream_url":"upstream_url is not a url","name":"name must only contain alphanumeric and '., -, _, ~' characters"}

I tried all combinations for upstream url ("testapi", "www.mydomain.com", etc) but still keep getting this error. Any ideas?
