title: Google Directions Service w/ Waypoints returning ZERO_RESULTS
body: <p>I currently have a DirectionsRenderer function that properly routes To and From fields on my page. After the routing is done I grab the overview_path and then load elements from a Fusion Table based on the path. Once this is done I've set up a listener looking for 'directions_changed', which would indicate a waypoint as such:</p>
  
  <pre><code>google.maps.event.addListener(directionsDisplay, 'directions_changed', function(){
  
          var wypnt = directionsDisplay.getDirections().routes[0].legs[0].via_waypoints.toString().match(/[^()]+/);
          wypnt.toString().split(",");
          wypnt = new google.maps.LatLng(wypnt[1],wypnt[0]);
  
          var waypoint = [];
  
          waypoint.push({ location: wypnt, stopover: true });
  
          route(waypoint);
      });
  </code></pre>
  
  <p>Once I pass it back to the route() function (the function that works normally with the To and From fields), I have this section of code:</p>
  
  <pre><code>if(waypoint){
  
      var request = {
          origin: document.getElementById("search-input-from").value,
          destination: document.getElementById("search-input-to").value,
          waypoints: waypoint,
          optimizeWaypoints: true,
          travelMode: google.maps.DirectionsTravelMode.DRIVING
      };
  }
  else{
  
      var request = {
          origin: document.getElementById("search-input-from").value,
          destination: document.getElementById("search-input-to").value,
          travelMode: google.maps.DirectionsTravelMode.DRIVING
      };
  }
  </code></pre>
  
  <p>The rest of the code is based off the following if statement:</p>
  
  <pre><code>directionService.route(request, function(result, status) {
      if (status == google.maps.DirectionsStatus.OK) {
  
         //do stuff
  
       }
      else {
                  alert("Directions query failed: " + status);
              }
      };
  </code></pre>
  
  <p>Unfortunately all I'm getting back is "Directions query failed: ZERO_RESULTS". Any idea why this is happening? I'm not sure if the way I'm forming the waypoint is wrong or something else.</p>
