System.Exception: Call to Node module failed with error: Error: Cannot find module C:\Windows\TEMP\tmpE99E.tmp #857

We have an angular2 app using Javascript services with .Net Core 1.1.0 and running on top of IIS 8.0 however after a few days it's crashing with an error. I've verified and tried the following to resolve the issue; Without success.

• restarting IIS app pool
• restarting website
• republishing website
• ensuring node is in the system path

This is particularly puzzling because the application has been working for a few days before we ran into this failure. Full callstack is published below:
