}).catch(function(err){
  /* You would normally NOT have a catch-all error handler like this - this is purely for the sake
   * of example. Normally, your error handlers would only catch those errors that it is specfically
   * interested in; an example of this is at https://gist.github.com/joepie91/f6a56acdae303e90e44a */
