Google pay library to scan debit/credit card details like card number, expiry date and CVV, facing an issue on Production its working on QA

Question

I have implemented the google pay library to scan debit/credit card details, its working fine in the QA environment but when I try to test it on production I am facing a crash.

https://developers.google.com/pay/payment-card-recognition/debit-credit-card-recognition

private fun createPaymentsClient(activity: Activity): PaymentsClient {
        val walletOptions = Wallet.WalletOptions.Builder()
                           .setEnvironment(WalletConstants.ENVIRONMENT_PRODUCTION)
                           .build()
        return Wallet.getPaymentsClient(activity, walletOptions)
    }

when I change environment to "WalletConstants.ENVIRONMENT_PRODUCTION" from "setEnvironment(Constants.PAYMENTS_ENVIRONMENT)" facing the crash below is crash log
