title: Webpack-dev-server- Module build failed
body: <p>I am getting the error</p>
  
  <p>---Error is below</p>
  
  <pre><code> ERROR in ./src/main.ts
  Module build failed: [object Object]
   @ multi webpack-dev-server/client?http://0.0.0.0:0 ./src/main.ts
  ERROR in ./src/polyfills.ts
  Module build failed: [object Object]
   @ multi ./src/polyfills.ts
  </code></pre>
  
  <hr>
  
  <p>Below is my webpack.config.js</p>
  
  <pre><code>module.exports = {
      devServer: {
          host: '0.0.0.0',
          disableHostCheck: true
      },
      entry: [
          'webpack-dev-server/client?http://0.0.0.0:4200',
          config.paths.demo
      ]
  }
  </code></pre>
  
  <p>My main.ts and polyfills.ts seem to be all right, I've checked for any errors which there don't seem to be any in those files. My guess is that there is something wrong in my webpack-dev-server.</p>
  
  <p>Does anybody have any suggestions on how to fix this?</p>
