I put together a tutorial on building a sleep tracker for your dog using Tessel and Twilio. Had a ton of fun building this, hope you all like it!

What version of the twilio library did you use? It's a problem with underscore:

I figured it out. The 1.8 underscore version brought hell: https://github.com/jashkenas/underscore/issues/2062

So if you npm i --save underscore@1.7, everything is fine.

Note that I had to do a

$ npm uninstall twilio
$ npm i --save underscore@1.7
$ npm install twilio -s

This is apparently needed since npm will not install the underscore that comes with twilio if it is already installed. Thus, I removed twilio + reinstalled after installing underscore 1.7.
