System.AggregateException

[ryanfalzon]

The below exception is being returned when I execute the following code: var client = new TradeApi(publicKey, privateKey); var _trades = client.GetTrades(CurrencyPair.Parse("XRP_BTC"), startDate, endDate).Result;

System.AggregateException HResult=0x80131500 Message=One or more errors occurred. Source=mscorlib StackTrace: at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task1.GetResultCore(Boolean waitCompletionNotification) at System.Threading.Tasks.Task1.get_Result() at KpmgKY.PrivateApiTool.Service.Services.PoloniexService.GetTradeHistory(String publicKey, String privateKey, DateTime startDate, DateTime endDate) in C:\KpmgKY.Development\KpmgKY.PrivateAPITool\src\KpmgKY.PrivateApiTool.Service\Services\PoloniexService.cs:line 48

Inner Exception 1: JsonSerializationException: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[CCXT.NET.Poloniex.Trade.TradeOrder]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object. Path 'error', line 1, position 9.

The error that occurred is when response is empty. I have uploaded and modified this.

How come the GetTrades method for Poloniex does not return a Date of when the transaction occured?

Below class has date property. You can use this. (ex) var _tranction_date = trades.result[0].date;

    public class PTradeOrderItem : IPTradeOrderItem
    {
        /// <summary>
        /// 
        /// </summary>
        public string gloablTradeId
        {
            get;
            set;
        }

......
        /// <summary>
        /// 
        /// </summary>
        public string category
        {
            get;
            set;
        }

        /// <summary>
        /// 
        /// </summary>
        public DateTime date
        {
            get;
            set;
        }
    }

Leave here json result string. (_json_value)

            var _json_value = await TradeClient.CallApiPost1Async(__end_point, _params);

            var _json_result = TradeClient.GetResponseMessage(_json_value.Response);
            if (_json_result.success == true)
                _result = await TradeClient.CallApiPostAsync<List<PTradeOrderItem>>(__end_point, _params);

I updated bug line like below.

 var _json_value = await TradeClient.CallApiPost1Async(__end_point, _params);

            var _json_result = TradeClient.GetResponseMessage(_json_value.Response);
            if (_json_result.success == true)
                _result = TradeClient.DeserializeObject<List<PTradeOrderItem>>(_json_value.Content);
