issue resolved by replacing
import * as fromInternal from './internal';
fromInternal.helpReducer

with
import { helpReducer } from './internal/help-center';

any help way this was happens

Hi @alyahmedaly,

I have the same issue, but I can't figure out where it's coming from.

How did you manage to find where was you issue? Also I don't have any import * in my code.

[alyahmedaly]

• disabled source map using -sm false
• enabled chrome pause on exceptions
  start debugging and found "helpReducer" came with null
  i guessed it :)

for you the issue seems to be related to an import in app.menu.ts try to deep import campaign.service.ts
sorry for my bad english

The root cause of this issue is a bug in webpack 2.2.0-rc3 which has now been fixed in RC4: https://github.com/webpack/webpack/issues/3895

@hansl @filipesilva I modified my local angular-cli to use webpack 2.2.0-rc4 and it cleared the run time error perfectly. Many ng2 devs on github and gitter are experiencing these issues from the same root cause after upgrading to ng cli beta 25.5. Can you guys fast track this webpack dependency upgrade in the ng CLI codebase?
