node-build-monitor: body.value undefined

I’m getting the following error for our on-site TFS2015 build server. I get this with the latest release for windows, linux, and directly running from node on a Raspberry Pi.

Have I not configured it correctly? It exits with this error with the several valid log-ins I have tried and for all my projects that I am able to view from a browser at the given url.
