title: Could not load the default credentials? (Node.js Google Compute Engine tutorial)
body: <p><strong>SITUATION:</strong></p>
  
  <p>I follow this tutorial: <a href="https://cloud.google.com/nodejs/tutorials/bookshelf-on-compute-engine" rel="noreferrer">https://cloud.google.com/nodejs/tutorials/bookshelf-on-compute-engine</a></p>
  
  <p>Everything works fine until I do <code>npm start</code> and go to:</p>
  
  <p><a href="http://localhost:8080" rel="noreferrer">http://localhost:8080</a></p>
  
  <p>I am met with the following text on the blank page:</p>
  
  <pre><code>Could not load the default credentials. Browse to https://developers.google.com/accounts/docs/application-default-credentials for more information.
  </code></pre>
  
  <p>Which makes no sense since I am using OAuth. I followed the link and read the page, but I have no <code>GOOGLE-APPLICATION-CREDENTIALS</code> field anywhere, and nothing about it in the tutorial.</p>

  <p><strong>QUESTION:</strong></p>
  
  <p>Could you please reproduce the steps and tell me if you get the same result ?</p>
  
  <p>(takes 5 minutes)</p>
  
  <p>If not, what could I have done wrong ?</p>
