解决方案
Change the MODE to Walking , Transit, Bicycling in your request.First check the output using google directions APIs endpoint on your browser.Walking and Bicycling results are not available for every pair of locations.
Appending the last part of your travelMode: google.maps.TravelMode."Change here".enter link description hereIf iteration(loop) is not possible repeat the code thrice.
