Heroku deployment failed with Angular4

[pascalgrimaud]

Overview of the issue

With the recent changes on production build, a fresh application with Angular4 can't be deployed to Heroku

Motivation for or Use Case

When trying to deploy to Heroku, I got this error:

@jdubois : do you think we need to do a new release for that? Or can we wait?
