With the Angular template I'm now receiving the following error when publishing to Azure via VSTS. This same build was working about 4-6 weeks ago. Nothing has changed on my end. Publishing via VS (Publish Profile) works fine.

I'm wondering if something in my template (webpack/certain package) needs to be upgraded to support VSTS? Not sure what else it could be unless something on VSTS changed.
