UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'model' of undefined

[awatson1978]

Hello,
So, I have the ECQM Engine running successfully, with both MongoDB and RabbitMQ, using node bin/rabbit_worker.js.

However, I'm receiving the following errors when I try to run the jasmine tests using npm run-script test:

Are there any extra command options we're suppose to be using when running the jasmine tests? I've tried using a environment variables such as NODE_ENV=test node bin/rabbit_worker.js.
