System.ArgumentNullException: Value cannot be null. (Parameter 'source') in CancelFuturesOrderByClientOrderIdAsync

[EricGarnier]

Hi Jan,
I recently bump into an exception while using the CancelFuturesOrderByClientOrderIdAsync method on IFuturesOrderClientIdRestClient

Below is the stack trace, but unfortunately, I didn't collect the exchange with the place.

Looking into the code, I suspect that is because CoinEx responded with a null Data, and the line
return order.AsExchangeResult(Exchange, request.Symbol!.TradingMode, new SharedId(order.Data.FirstOrDefault()?.Data?.Id.ToString() ?? request.OrderId));
crashed on the FirstOrDefault.
Maybe you could protect the code for this case ?

In any way, this is not a hurry for me.

Thanks for all your efforts.

Eric
