title: Google Drive API Listing Files with Field Paramter Not Working
body: <p>I am currently listing some files with the Google Drive API. However, the default list only lists <code>id</code>, <code>name</code>, and <code>mimeType</code>. I know that the <code>fields</code> parameter can list more than just the default, but when I put <code>parents</code> as a field in the Google API Playground, I get the error of <code>Invalid field selection parents</code>. However, when I use <code>*</code> in the <code>fields</code> parameter, it returns all the fields. Am I doing anything wrong by putting <code>parents</code> in the fields parameter? If so, does anyone have any idea how to include the <code>parents</code> field as a field in the list results?</p>
  <p>Here is my current endpoint, which causes the error:</p>
  <pre><code>https://www.googleapis.com/drive/v3/files?fields=parents&amp;key=[YOUR_API_KEY]
  </code></pre>
  <p>Thanks!</p>
