title: Google Directory API users endpoint sometimes doesn't return orgUnitPath
body: <p>I have setup watch channels for the User resource via the Google Directory API to receive push notifications when the resource changes or is created.</p>
  
  <p>When my app receives a notification, it reads the e-mail of the user which was changed/created, then calls the users.get endpoint of the Directory API to get the latest data for that user and finally updates my database with that data.</p>
  
  <p>In most cases this flow works fine, but I've observed that every now and then when a new user is created, the response from the users.get endpoint does not include the orgUnitPath property. It's not set to null, it's not even there. However, if I hit the endpoint again a while later, the property is there. </p>
  
  <p>Does anyone know why this happens?</p>
