title: Error: Unexpected value 'Http' imported by the module 'AppModule' at SyntaxError.ZoneAwareError
body: <p>I've checked my code several times and tried finding similar problems on the web and stackoverflow, but I'm out of ideas by now, I simply can't see my mistake. Do you have any recommendations what I should examine next?</p>
  
  <p>UPDATE: When I debug my Configuration Class I can see, that my json-Configurations files are read and the values are stored into my configuration variables correctly on App-Initialize (see load()-function of app.config.ts on plnkr).
  BUT if I want to get the values back from this configuration varibales e.g. line 39 of "werkzeug.service.ts" </p>
  
  <pre><code>let host:string = this.config.getConfig('host');
  </code></pre>
  
  <p>The following error appears:</p>
  
  <pre><code>TypeError: Cannot read property 'host' of null
