Steps to Reproduce

Heroku builds getting failed whenever there is a PR up in micromaster repository. We need to trace out the reasons for this failure.

Expected Behavior

Build should be deployable without any error like mitxpro, mitxonline etc.

Actual Behavior

Build are not getting passed for any pull request.

For testing, I created a Testing PR to identify the reasons but not much from the logs. In the PR, I tried to install the node packages from npm instead of using yarn and the build complains about 2 things.
