[yousra-h]

Describe the bug
I tried retrieving a snapshot but the BinanceOrderBook result had an empty "Symbol" value

To Reproduce
BinanceSocketClient binanceSocketClient = new BinanceRestClient();
Then i tried to retrieve the snapshot, I called binanceSocketClient.SpotApi.ExchangeData.GetOrderBookAsync("BTCEUR",30);
The BinanceOrderBook response has an empty value on the field "Symbol"
