Apple Pay provisioning error

Hi,

I can't complete provisioning flow on Sandbox Environment. You can find error response and PKAddPaymentPassRequestConfiguration below. How can I find the issue?

guard let addPaymentPassRequestConfiguration = PKAddPaymentPassRequestConfiguration(
            encryptionScheme: .ECC_V2
        ) else { return }

        addPaymentPassRequestConfiguration.style = .payment

        addPaymentPassRequestConfiguration.cardholderName = debitCard.cardholder
        addPaymentPassRequestConfiguration.primaryAccountSuffix = String(debitCard.cardNumber.suffix(4))
        addPaymentPassRequestConfiguration.localizedDescription = debitCard.cardType.cardDisplayName
        addPaymentPassRequestConfiguration.paymentNetwork = .girocard
