Hello,

I am using Merchello version 2.4.0 and I have an error getting the shipment rates. I am using the code below and the method shipment.ShipmentRateQuoteByShipMethod(item.Key, false) always throws a null exception.

  var key = Merchello.Core.Constants.ProviderKeys.Shipping.FixedRateShippingProviderKey;
        var rateTableProvider = MerchelloContext.Current.Gateways.Shipping.GetProviderByKey(key);
        var shippingMethods = rateTableProvider.ShipMethods;
        var shipment = this.Basket.PackageBasket(shippingAddress)?.FirstOrDefault();
        if (shipment != null)
        {
            var item = shippingMethods.Where(s => s.Name == "Standard Shipping").FirstOrDefault();
            var shipmentRate = shipment.ShipmentRateQuoteByShipMethod(item.Key, false);

}
