Hi, I'm using Esri ArcGIS Runtime Version 100.15 (WPF) and trying to integrate OGC Layers into my App.
I'm creating the layer as follows:
var featureTable = new OgcFeatureCollectionTable(new Uri(layer.Path), layer.Layers);
var featureLayer = new FeatureLayer(featureTable);
MapView.Map.OperationalLayers.Add(featureLayer);
This works with the following Demo-Service: https://demo.ldproxy.net/daraa (Layer: AeronauticCrv)
But with my Service, I'm getting the Error: Esri.ArcGISRuntime.ArcGISRuntimeException: JSON parser invalid token: Error processing OGC_feature service JSON response
The layer ist hosted on a QGIS Server.
In the background there are three requests made by ArcGIS (random order):

I also tried to load the layer in the online ArcGIS MapViewer but this also didn't work and didn't give me any more information.
Does anyone have an Idea what the problem could be? What are the conformance requirements of the .Net Maps SDK?
