1. Repro steps. Tell us exactly what you did and how you came to the failure.

after upgrading our project to angular2 rc.1 and angular-cli 1.0.0-beta, the -prod option no longer works. We get a completely mysterious error message which does not give us enough information to even guess at what the problem is:

$ ng server --prod

(We see the same with node 4.4.3 and 5.x)

All of the classes referenced there come from/via a2 and/or angular-cli - none of them are from our tree.

If you can give us steps from the moment you created an empty application, even better!

Unfortunately this does not happen with a clean-slate (ng new) app, but:

a) we updated our application by using (ng new) and copying our sources over to the new tree.

b) non-prod builds and runs just fine, so we have to assume the problem is somewhere internally in the handling of the prod environment (which we do not manipulate, other than to add 2 empty functions to the environment object in config/environment.prod.ts). Unfortunately, ng does not support custom environment names (--environment=mine), so attempts to reproduce it (or rule it out) that way have failed.

c) we’ve gone through and compared our config files with those of a clean-slate build literally 5 times, and the only difference is that our app lives under src/client/app instead of src/app (i’m told by our maven gurus that that’s necessary for our particular build environment).

Because the error message is so cryptic (and contains no mention of classes/files from us), we have literally no idea where to start looking. Any hint for how we can tickle more info out of -prod would be much appreciated.
