Apple Pay Error 153 :There was an error processing the payment data. Unable to decrypt data.

[akay]

I have successfully enabled the apple pay integration in sandbox account by following the In-App guide.

But I am getting error during transaction: 

There was an error processing the payment data. Unable to decrypt data.

I am using below ios code to get payment token:
let transactionIdentifier = payment.token.transactionIdentifier

let base64str = self.base64forData(payment.token.paymentData)

and using payment.token.paymentData as OpaqueDataValue parameter in backend API.

Please help.

Were you able to solve this? I'm running into the same issue. Already regenerated certificates and no luck
