string to RenderUrl error?

[StealthyXor]

var ids = webApiClient.Items.IdsAsync().Result;
var items = webApiClient.Items.ManyAsync(ids).Result;

exception occurs on GW2Sharp.Json.Converters.CastableTypeConverter

var targetType = objectType.GetCustomAttributes<CastableTypeAttribute>().FirstOrDefault(a => a.Value.Equals(type.ParseEnum(a.Value.GetType())))?.ObjectType;
            return targetType == null ? jObject.ToObject(objectType) : jObject.ToObject(targetType, serializer);

where:
targetType = null
and error message is:

Newtonsoft.Json.JsonSerializationException
