Wappler cant fetch the schema of this JSON data

Hi, i cant fetch the schema of this json data that i got from the horrible service of google Matrix API .
Here is the documentation https://developers.google.com/maps/documentation/distance-matrix/overview?hl=es-419

This is the json data:

{
   "destination_addresses": [
      "Lavalle 1735, C1048AAO CABA, Argentina"
   ],
   "origin_addresses": [
      "Roque Sáenz Peña 484-88, B1636FFB Olivos, Provincia de Buenos Aires, Argentina"
   ],
   "rows": [
      {
         "elements": [
            {
               "distance": {
                  "text": "16.6 km",
                  "value": 16644
               },
               "duration": {
                  "text": "25 min",
                  "value": 1519
               },
               "status": "OK"
            }
         ]
      }
   ],
