Adding Card to Apple Wallet is failing in Sandbox

I work for a bank application, we are trying to add the card to apple wallet programatically, we have generated the certificates, nonce and nonceSignature and able to ger empherialKey, activationData and encryptedPassData from our servers. Now when I'm calling the handler with PKAddPaymentPassRequest, I'm getting the error Your Card Issuer Does Not Yet Offer Support for This Card. I'm testing this in Sandbox environment. Can you please help me ?

To help resolve this we would need additional information and device logs. If you have an existing Apple contact who has been helping you with in-app provisioning please reach out to them. If you do not, please file a Technical Support Incident (https://developer.apple.com/support/technical/) along with diagnostic logs (https://developer.apple.com/documentation/xcode/acquiring-crash-reports-and-diagnostic-logs).

Hello, I was wondering how the values of your encryptedPassData and empherialKey attributes are generated? I mean, like encryptedPassData, how is this encrypted and generated? thank you
