Fetching all the coordinates along a route generated by Directions Service in Google Maps Apiv3

My application allows a user to select two points on the map and find a route between them using the Directions Service of the Google maps Apiv3. Then the coordinates along this route has to be saved to the database. I could successfully write all the code to accomplish this. However I am left out with an issue. I know that there are several other questions in StackOverflow- One, Two on the same, but I think surely either they or me has missed out something here. Sample Code: ``` function getCoordinates(result) { var currentRouteArray = result.routes[0]; //Returns a complex object containing the results of the current route var currentRoute = currentRouteArray.overview_path; //Returns a simplified version of all the coordinates on the path obj_newPolyline = new google.maps.Polyline({ map: map }); //a polyline just to verify my code is fetching the coordinates var path = obj_newPolyline.getPath(); for (var x = 0; x < currentRoute.length; x++) { var pos = new google.maps.LatLng(currentRoute[x].kb, currentRoute[x].lb) latArray[x] = currentRoute[x].kb; //Returns the latitude lngArray[x] = currentRoute[x].lb; //Returns the longitude path.push(pos); } } ``` The above code works perfect except that the `kb` and `lb` properties of the overview path which seem to hold the lat and lng coordinates are not always the same. The last time I made the code, it was `kb` and `lb` for few days, and later it changed to `mb`, `nb` and today `jb` and `kb`. I dont see any other properties in the object that can provide me the latlng's other than the above. Answers to other similar questions dint mention this issue. Am I missing something here? Any reliable solutions please.
