title: Can't get Compute Engine instances list
body: <p>I'm testing out Compute Engine and am hitting a snag. I've set up a project (jwl-project-1) and created an instance (instance-1). After authenticating with gcloud auth login, I set the project like this:</p>
  
  <pre><code>gcloud config set project jwl-project-1
  </code></pre>
  
  <p>And then tried to get a list of instances:</p>
  
  <pre><code>gcloud compute instances list
  </code></pre>
  
  <p>In return, I get this error:</p>
  
  <pre><code>ERROR: (gcloud.compute.instances.list) Some requests did not succeed:
  - Invalid value for project: jwl-project-1
  </code></pre>
  
  <p>I basically accepted the default values for project and instances (micro-disk). What am I missing?</p>
