2. Repro steps. Was this an app that wasn't created using the CLI? What change did you
   do on your code? etc.
   I have built a small but extensive application. I am attaching some of the configuration files. Please let me know if you need more.

I ran ng init just to make sure I had everything for the CLI.
ng build -prod
