posDevice.Sale method return null in iCT250 ingenico

fadime-ozdemir opened this issue · comments

Hello,
I applied the as it is shown in the readme, I changed the SaleResponse to SaleResult because there wasn't any SaleResponse class.
However, I still got posDevice.Sale result null.
Should It return Success false if the transaction is unsuccessful and true if it is successful?
How can we solve this problem?
