Sencha Build Fails "def was null"

[2b3pro]

As I am trying to deploy my application with Sencha Cmd 3.0.2.288

sencha build app production

I am getting this error stopping everything in its tracks:

Compiling app.js and dependencies

I don't understand how this null.controller.Video could be true since the controller is defined within the app namespace and not "null". Where does this come from?

I have no clue as to how to troubleshoot this. Can someone advise? Thank you.

There was an error in my app.json file where the application name was not correctly assigned.
