JSON response being truncated

Reproduction Steps

using Azure;
using Azure.Core.GeoJson;
using Azure.Maps.Routing;

AzureKeyCredential credential = new AzureKeyCredential("<credentials>");
MapsRoutingClient routeClient = new(credential);

RouteDirectionOptions azureRouteOptions = new()
{
	TravelMode =  TravelMode.Truck,
	InstructionsType = RouteInstructionsType.Text,
	Language = RoutingLanguage.EnglishUsa,
	UseTrafficData = false,
};

GeoPosition origin = new(-88.3, 41.92);
List<GeoPosition> geoPositions = [
	new(-111.38, 47.65),
	new(-111.34, 47.26),
	new(-111.25, 47.48),
	new(-112.6, 47.58),
	new(-113.37, 48.78),
	new(-110.87, 47.26),
	new(-111.26, 47.53),
	new(-111.57, 48.02),
	new(-113.27, 48.59),
	new(-109.92, 46.8)
];

List<RouteDirectionQuery> queries = [];

foreach (var destination in geoPositions)
{
	queries.Add(new RouteDirectionQuery([
				new GeoPosition(origin.Longitude, origin.Latitude),
				new GeoPosition(destination.Longitude, destination.Latitude)],
				azureRouteOptions));
}


var response = routeClient.GetDirectionsBatch(WaitUntil.Completed, queries);
