KrakenRestClient.SpotApi.Trading.PlaceOrderAsync error

[Piggy69]

When I send and order to Kraken using

await _krakenClient.SpotApi.Trading.PlaceOrderAsync(symbol, side,type,quantity,clientOrderId,price,secondaryPrice,**timeInForce**,**validateOnly=true**,ct)

I receive an error stating An item with the same key has already been added. Key: timeinforce

If I send the same order without specifying the timeInForce parameter, the call completes successfully.
Please note that I cannot remove and test the behavior without the validateOnly=true parameter (really first steps of Kraken integration).

The exact call is:
WebCallResult<KrakenPlacedOrder> dispatchResult = await _krakenClient.SpotApi.Trading.PlaceOrderAsync(symbol: dispatchArguments.Symbol, side: dispatchArguments.KrakenOrderSide, type: dispatchArguments.KrakenSpotOrderType, quantity: dispatchArguments.Quantity ?? 0, clientOrderId: Convert.ToUInt32(dispatchArguments.InternalOrderId), price: dispatchArguments.Price, secondaryPrice: dispatchArguments.Price2, timeInForce: Kraken.Net.Enums.TimeInForce.GTC, validateOnly: true, ct: cancellationToken);

Where the real values of the parameters are
symbol:BTCUSD
side: buy
type: limit
quantity: 0.001
price: 22220
secondaryPrice:null
clientOrderId (a long converted to uint)

The full exception stack is:

Hi, turns out there was indeed a bug in the PlaceOrder endpoint causing your issue. Should be fixed in the latest version
