title: Karma Start Fails - HeadlessChrome - ERROR Uncaught [object Object]
body: <p>I am using Karma to run test on my Angular 4 app. <strong>It works locally</strong> but when it runs on my host environment (Travis CI) it fails with the following information:</p>
  
  <pre><code>INFO [HeadlessChrome 0.0.0 (Ubuntu 0.0.0)]: Connected on socket vT0QnQaqRkn010dfsw with id 10189531

    Uncaught [object Object]
  
    at http://localhost:9876/_karma_webpack_/vendor.bundle.js:14078
  </code></pre>
  
  <p>I tried following the suggestions (deleting NPM cache, etc) from <a href="https://stackoverflow.com/questions/47873996/uncaught-object-object-when-running-karma-tests-on-angular">&quot;Uncaught [object Object]&quot; when running karma tests on Angular</a> but it did not solve my issue.</p>
  
  <p>How can I identify what is causing this <code>Uncaught [object Object]</code> error. What additional steps should I take to troubleshoot?</p>
