ReactNative with Stripe Google Pay

Question

We have implemented the stripe google-pay payment using in reactNative code. My code working fine with sandbox account but live environment suppose to not working. We followed this link: enter link description here

My code:

await confirmPlatformPayPayment(
            response.data.client_secret, // ClientSecret key from PaymentIntent response
            {
              googlePay: {
            testEnv: true,
            merchantCountryCode: 'US',
            merchantName: 'xyz',
            currencyCode: 'USD',
            billingAddressConfig: {
              format: PlatformPay.BillingAddressFormat.Min,
              isPhoneNumberRequired: true,
              isRequired: true,
            },
            isEmailRequired: true,
            }})

We are using front end reactNative and backend for PHP for paymentIntent create. When we execute the google pay checkout then we received following error

Error:

{"stripeErrorCode":null,"message":"Google Pay failed with error:","declineCode":null,"type":null,"localizedMessage":"Google Pay failed with error:","code":"Failed"}

Could you please help us resolved the issue?
