I'm trying to make a route between two points using HereMaps , so that's fine, I did, however, it does not go down the street, but across the map.

As I would have it to go down the street, in the documentation of HereMaps , the example works perfectly.

My code

let platform = new H.service.Platform({
    'app_id': '',
    'app_code': ''
})

let defaultLayers = platform.createDefaultLayers()
let map = new H.Map(
        document.getElementById('map'),
        defaultLayers.normal.map,
        {
            zoom: 15,
            center: {lat: -23.5627, lng: -46.6546}
        }
)

let behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));

if (this.habCaminho) {
    let routingParameters = {
        mode: 'fastest;truck',
        representation: 'display',
        waypoint0: "geo!23.56277,46.65459",
        waypoint1: "geo!" + marc1
    };

    let onResult = function (result) {
        let route,
                routeShape,
                startPoint,
                endPoint,
                linestring

        if (result.response.route) {
            route = result.response.route[0]
            routeShape = route.shape
            linestring = new H.geo.LineString()

            routeShape.forEach(function (point) {
                let parts = point.split(',')
                linestring.pushLatLngAlt(-parts[0], -parts[1])
            });

            startPoint = route.waypoint[0].mappedPosition
            endPoint = route.waypoint[1].mappedPosition

            let routeLine = new H.map.Polyline(linestring, {
                style: {strokeColor: '#045993', lineWidth: 5},
                arrows: {fillColor: 'white', frequency: 2, width: 0.8, length: 0.7}
            })

            let startMarker = new H.map.Marker({
                lat: -startPoint.latitude,
                lng: -startPoint.longitude
            })

            let endMarker = new H.map.Marker({
                lat: -endPoint.latitude,
                lng: -endPoint.longitude
            })

            map.addObjects([routeLine]);
            map.setViewBounds(routeLine.getBounds(), true);
        }
    }

    let router = platform.getRoutingService();

    router.calculateRoute(routingParameters, onResult,
            (error) => {
        alert(error.message);
    })
}

In the end, I managed to solve my problem, for those who have the same problem, follow the code.

function calculateRouteFromAtoB (platform) {
                    let router = platform.getRoutingService(),
                    routeRequestParams = {
                        mode: 'fastest;truck',
                        representation: 'display',
                        routeattributes : 'waypoints,summary,shape,legs',
                        maneuverattributes: 'direction,action',
                        language: 'pt-br'
                    }

                    for(let i = 0; i < posicoes.length; i++){
                        let name = "waypoint"+i

                        routeRequestParams[name] = posicoes[i].pos
                    }

                    router.calculateRoute(
                        routeRequestParams,
                        onSuccess,
                        onError
                    )   
                }

                function onSuccess(result) {

                    let route = result.response.route[0];


                    addRouteShapeToMap(route)
                    addPins(route)
                    //addInfo(route)
                }

                function onError(error) {
                    alert('Ooops!');
                }

                let defaultLayers = platform.createDefaultLayers()

                    })

                    map.addObject(polyline);
