Steps to Reproduce

1. Open your Develop Console to the "Networks" tab
2. Using latest webui/apiserver images, navigate to https://www.local.ndslabs.org/dashboard/home/?quickstart=owncloud

Expected Results

• After logging in, you should see a request to /start?key=owncloud that has returned with a 422 (Unprocessable Entity)

Actual Results

1. After logging in, I receive a popup saying that the service was not found and my "Networks" tab shows that that request has return with an HTTP 500 (Internal Server Error)
2. Running through the same test case, willis8 was receiving a 404 back from the same request
3. In the apiserver logs, I see a stack trace:

   runtime error: invalid memory address or nil pointer dereference

Potential Cause(s)

1. Following this stack trace down, we see that the line that fails seems to be this one: https://github.com/nds-org/ndslabs/blob/c1b2ef046d1cab842983376b843197765f1e5f22/apiserver/cmd/server/server.go#L2086
   • Is it possible that this integer "422" is unexpected, and that the method instead expects "http.StatusUnprocessableEntity"? (see https://golang.org/pkg/net/http/ - maybe these are simply aliases for the constant values)
