[velocity] Parent Handshake response undefined undefined

I’ve installed velocity:html-reporter mike:mocha sanjo:jasmine, however velocity never shows the results of the tests, the blue dot throbs forever. It is able to find the test files which is lists out (not in the screenshot).

When running using the debug flag, (VELOCITY_DEBUG=1 iron, aka VELOCITY_DEBUG=1 meteor) I found this line in the debug: [velocity] Parent Handshake response undefined undefined

Any ideas why my test files aren’t running?
