title: Google Drive API insert permission only returns id
body: <p>I'm using this request to grant user permission for a folder</p>
  
  <pre><code>https://www.googleapis.com/drive/v2/files/{{id}}/permissions?sendNotificationEmails=true&amp;fields=emailAddress,id,name,role,type,value
  </code></pre>
  
  <p>but it returns only the id field</p>
  
  <p><code>{ id: '0123456789876543210' }</code> like this</p>
  
  <p>How can I get all other information in response ? or,
  is there any BUG in Drive REST API ?</p>
