Error creating RouteTask

Hello,

I'm writing a mobile Xamarin Android app that uses a network analysis service (NAS) to find routes.
This is my work environment:
Windows 10 Pro (v. 1809)
Visual Studio 2017 Community with Xamarin
ArcGIS Runtime SDK for .Net (v. 100.4.0; I also tried with v. 100.5.0)
Xamarin.Android... library packages (v. 27.0.2.1; I also tried with v. 28.0.0.1)
ArcGIS Server 10.5

The NAS uri is http://geoservizi.iuav.it:6080/arcgis/rest/services/network/venezia_network/NAServer/Route

To create a route task I use this code:

System.Uri myNasUri = new System.Uri("http://geoservizi.iuav.it:6080/arcgis/rest/services/network/venezia_network/NAServer/Route");
RouteTask solveRouteTask = await RouteTask.CreateAsync(myNasUri);

When I run the app I catch this error:

Error: Esri.ArcGISRuntime.ArcGISRuntimeException: Internal error: Data type Unknown
at Esri.ArcGISRuntime.Tasks.NetworkAnalysis.RouteTask+<CreateAsync>d__11.MoveNext () [0x0005f] in C:\daily_r\api_xam\dotnet\api\src\Esri.ArcGISRuntime\Esri.ArcGISRuntime.Shared\Tasks\NetworkAnalysis\RouteTask.cs:100

If I use another (more simple) NAS at http://geoservizi.iuav.it:6080/arcgis/rest/services/network/test3_service/NAServer/Route no error occurs.

Moreover, if I load in ArcMap the NAS that causes the error, and then I try to find a route with the Find Route tool, everything works properly.

Any idea what can cause the error?

Many thanks.

Massimo

I'm having the exact same issue, only for WPF instead of android. My NAS works for 10.2.7 and in ARCMap

Massimo,

Please can you retest with 100.7?

Thanks

Michael,

I solved the problem by following the tips in this thread

Transit Evaluator app error on ArcGIS Server

Now the app run correctly using 100.x SDK version.

Best regards

Massimo
