When building for prod, the console outputs: Uncaught Error: Cannot find module "./app/app"

I'm working on a fairly fresh project using the webpack-starter, it works well when I'm in dev mode serving etc.

But when I build the prod code, serve it or move the files on an apache server I get the error:
Uncaught Error: Cannot find module "./app/app"

In the sources in chrome inspector, I only see main.ts and polyfills.ts in the src directory.
Anyone encountered this before, am I missing something?

I did not realise, that having some errors in usage of quotes, spaces etc. would cause the production build to fail.
