Steps to Reproduce:

  1. Clone [Design]Update CI configs to use node 10 aspnet/Templating#582 on a linux machine
  2. Run build.sh -ci

Expected Behavior: No Null-Refs, or a more descriptive error about what's going wrong.

Actual Behavior: System.NullReferenceException: Object reference not set to an instance of an object.
