title: Attach a pdf from google drive to an email using google apps script
body: <p>I'm using a custom created google apps script to send out some emails.  I have a PDF in my google drive that I am trying to attach to an email but it is not working.  I keep on getting the error "Document is missing (perhaps it was deleted?)"</p>
  
  <p>Here is my full code...</p>
  
  <pre><code>    function sendDetails(e) {
  var itemURL = 'https://docs.google.com/file/d/0Bw7JWLKeRBKASUFldGM1RTRIaFE/edit';
  var docName = DocumentApp.openByUrl(itemURL).getName();
  }
  </code></pre>
  
  <p>Note that the above PDF is a publicly accessible PDF file that anyone can get to.  I know it exists but it's not allowing me to access it.  All that I am trying to do is take the file and attach it to an email.  There is obviously more to my code than the about but I trimmed down just to that to try to narrow the error and no such luck.  Any help would be greatly appreciated.</p>
