"loadPaymentData error" Promise rejection from paymentRequest.show() with error message "8"

[max-nicholson]

Hi, we're seeing users getting "loadPaymentData error" promise rejections from paymentRequest.show() with an error message of "8", which isn't particularly clear to debug/fix. We've got a screenshot of the error screen the user sees below

It looks like this error comes from:

react-native-make-payment/android/src/main/java/com/makepayment/MakePaymentModule.kt

Line 67 in b8ea372

"loadPaymentData error",

Trying to search online for Google error codes, I've found this, which suggests 8 = "INTERNAL_ERROR".
https://developers.google.com/android/reference/com/google/android/gms/common/api/CommonStatusCodes#INTERNAL_ERROR()

1. Does this "8" actually map to INTERNAL_ERROR, or something else?
2. Is there anything we can do about this error? The INTERNAL_ERROR docs suggest retries - would that be calling await paymentRequest.show() in a retry loop?
3. Would it be possible to improve the thrown error to include more information for debugging purposes (e.g. is there a reason we only get an "8" when the user is seeing an "RpcClientException", would we be able to add other fields to the error object e.g. an error.code)?

@max-nicholson are you able to reproduce this issue? or do you have a timestamp + user email so I can check our logs?

@dmengelt no, I haven't personally reproduced this.

Is there a more secure channel I can share some examples (since it's customer PII)?
