API Problem HereMaps Javascript

I'm having trouble displaying the line between two points, when I use any Lat / Long without the "-", it works, but when I get a (-23.563210, -46.654250) that has "-", it does not work anymore.

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));

            let routingParameters = {
                mode: 'fastest;car',
                waypoint0: "-23.56277,-46.65459",
                waypoint1: '52.5206,13.3862',
                representation: 'display',
                routeattributes: 'waypoints,summary,shape,legs',
                maneuverattributes: 'direction,action'
            };

            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: 'blue', lineWidth: 10 }
                    })

                    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, startMarker, endMarker]);
                    map.setViewBounds(routeLine.getBounds());
                }
            }

            let router = platform.getRoutingService();

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