UnknownError returned from RouteModel

alegria

Hey everyone,

I am developing a project for my term project and in one of the modules it gets two coordinates from me, finds the shortest path and shows the route. But for about a week now, the plugin doesn't seem to draw any route. I tried running a routing query on OSM website which worked just fine. Thing is when I use GeocodeModel it works just fine but when it comes to RouteModel, it does not draw the path between coordinates also sets the "status" in routeModel to 3 -which is RouteModel.Error-, "error" to 5 -which is RouteModel.UnknownError- and "errorString" to "Found route between points".
I tried tracing packets using WireShark -as Mr.Aaron McCarthy from QtLocation asked- and there is no json file directed to my IP from server.

Any ideas on how can I overcome this issue ?
Many thanks in advance.

Hi and welcome to devnet,

Without any code it's pretty difficult, can you provide a small compilable example that shows that behavior ?

Thanks. I didn't add the code because it's the code Laszlo Agocs implemented in this video . I assumed the error QT-related. Anyway here's the code :

Item {
    property variant fromCoordinate : QtPositioning.coordinate(-27.579336,153.100333);
    property variant toCoordinate : QtPositioning.coordinate(-37.759136, 145.156359);
    PositionSource{
        active:true
        onPositionChanged: { console.log(position.coordinate);}
    }
    Map{
        id:map
        plugin: Plugin{
            name: "osm"
            }
       center {
            latitude: -27.5796
            longitude: 153.1003
        }
        zoomLevel: 15
        gesture.enabled: true
        anchors.fill:parent
        MapQuickItem{
            id:marker
            opacity: 0.6
            coordinate:QtPositioning.coordinate(-27.579622,153.10032);
            sourceItem: Image {
                id:image
                source: "qrc:/resources/arrow.png"
            }
            anchorPoint.x: 0
            anchorPoint.y: image.height/2
        }
        MapItemView{
            model: routeModel
            delegate: Component {
                MapRoute{
                    route:routeData
                    line.color:"blue"
                    line.width: 4
                }
            }
        }
    }    
    RouteModel
   {
       id:routeModel
       plugin: map.plugin
       query:RouteQuery{
           id:routeQuery }
       autoUpdate: true
       Component.onCompleted: {
           routeQuery.addWaypoint(fromCoordinate);
           routeQuery.addWaypoint(toCoordinate);
           update();           
       }      
   }
}

Sorry it's a bit long. Thanks for your interest.

Edit: The lines I logged error values I mentioned above aren't included for the sake of clarity.

Update -
So, an interesting thing happened. I was tracing the packets in and out on my network, I filtered the ones whose ip:"141.3.85.1" -which i think is the routing server- the packets sent to me from this source includes a application.json file. Inside the file is the route between my coordinates.
tags included in the file is here

Up!
So anyone catches sight of the topic.

I've tested your code but I can't reproduce your error, so it might indeed but something in your current network setup.

Hi, any progress in the last months? I have the same problem with example code from http://doc.qt.io/qt-5/qgeoroutingmanager.html#details

Alexander_Lanin

ah it's fixed in 5.6.0 RC: https://bugreports.qt.io/browse/QTBUG-50240
