@TuxOtaku Did you ever fix this? Just run into the same issue myself, almost a year later.

I just spent a few days debugging this for a project of mine. I found that the error was that I had a node package in my external-scripts which was not a hubot script, so hence the "not a function" error. Hope this helps.
