Apple Pay crash: [General] Payment request is invalid: Error Domain=PKPassKitErrorDomain Code=1 "(null)"

[Ariandr]

Summary

Hello, we get a crash [General] Payment request is invalid: Error Domain=PKPassKitErrorDomain Code=1 "(null)" on iOS when trying to pay using Apple Pay as a payment method.

The merchant identifier is correct, the certificate in Stripe console is valid, the capability is enabled in Xcode.
We use STPPaymentContext and Stripe UI to select/add payment methods.

Code to reproduce

Call this when Apple Pay payment method is selected.
paymentContext.requestPayment()

iOS version

iOS 12.4.1-13.2.3, both real devices and simulators

Installation method

Cocoapods

SDK version

18.3.0

Other information

The integration was done according to this guide: https://stripe.com/docs/mobile/ios/basic#set-up-apple-pay

For testing we created a sandbox user according to this guide from Apple (https://developer.apple.com/apple-pay/sandbox-testing/), set up test the wallet and card
(FPAN: 5204 2477 5000 1471
Expiration Date: 11/2022
CVC: 111).

Also tried testing on a real Apple Id with the real wallet and cards, the same error every single time.

What can be the issue? Do we need to setup anything else which is not mentioned in the Basic Integration guide?

Found a workaround here, though it's not perfect.
