Leaflet and Valhalla web app routes issue

I'm trying to integrate the Valhalla web app with Leaflet and I have some issues with drawing the right route. I want to create a pedestrian route so I call the api https://valhalla1.openstreetmap.de after creating the json. The issues are:

The points are connected well, but the routes are not drawn correctly (they don't follow the street)
If I change the "costing" value nothing change

My resulting json is

{
   "costing":"pedestrian",
   "locations":[
         {"lon":"14.207994","lat":"41.110242","type":"via"},
         {"lon":"14.208491","lat":"41.109895","type":"via"},
         {"lon":"14.211598","lat":"41.107943","type":"via"},
         {"lon":"14.211446","lat":"41.108951","type":"via"},
         {"lon":"14.212708","lat":"41.109952","type":"via"},
         {"lon":"14.213006","lat":"41.110424","type":"via"},
         {"lon":"14.212892","lat":"41.11096","type":"via"},
         {"lon":"14.213697929872753","lat":"41.10965172126981","type":"via"},
         {"lon":"14.217564","lat":"41.106637","type":"via"},
         {"lon":"14.2126","lat":"41.107311","type":"via"},
         {"lon":"14.207614599551142","lat":"41.10673799401134","type":"via"}
    ],
   "language":"it-IT",
   "id":"map_routes"
}

Then I draw the leaflet polyline with the result (that seems correct) L.polyline(result.trip.locations, {color: '#eb0000'}).addTo(map);

But I get this (it seems it doesn't follow the streets)

I can't figure out what I'm doing wrong. Can you help me?

Not sure I understand: this is a web app already, which implements leaflet. Sounds like you’re doing your own app, so it’s not an issue with this project?
