Transactions are being canceled during the antifraud analysis due to missing essential information in the billingAddress.

The billingAddress is sent during the payment process and can either be a copy of the shippingAddress if the user chooses not to differentiate them (by marking isBillingAddressDifferent as false) during checkout. Alternatively, it can be a new address provided by the user if the isBillingAddressDifferent option is marked as true. This address is used in the antifraud authorization request, and the absence of mandatory information can lead to transaction cancellations.

We have observed that this behavior occurs with payments made using new cards, which have not been previously saved in the store, and when the user chooses not to differentiate the addresses (isBillingAddressDifferent: false). Importantly, the shippingAaddress contains all the required fields correctly filled out, while the billingAddress, which should be a copy of the shippingAddress, remains incomplete.
