I am struggling to understand this error. I am getting following josn from my back-end server using Ajax call

    "supportedNetworks": [
        "amex",
        "discover",
        "maestro",
        "masterCard",
        "visa"
    ],
    "requiredShippingContactFields": [
        "email",
        "name",
        "phone",
        "postalAddress"
    ],
    "requiredBillingContactFields": [
        "postalAddress"
    ],
    "merchantCapabilities": [
        "supportsCredit",
        "supportsDebit",
        "supports3DS"
    ],
    "shippingContact": {
        "phoneNumber": "111-111-1111",
        "emailAddress": "***@gmail.com",

}

Here is my code to create Apple Pay session

this.session = new ApplePaySession(3, var2);

While running this code, I am getting following error on the js: TypeError: Member ApplePayPaymentRequest.countryCode is required and must be an instance of DOMString

If I change the code and hard code the same json coming from Ajax call as :

    "supportedNetworks": [
        "amex",
        "discover",
        "maestro",
        "masterCard",
        "visa"
    ],
    "requiredShippingContactFields": [
        "email",
        "name",
        "phone",
        "postalAddress"
    ],
    "requiredBillingContactFields": [
        "postalAddress"
    ],
    "merchantCapabilities": [
        "supportsCredit",
        "supportsDebit",
        "supports3DS"
    ],
    "shippingContact": {
        "phoneNumber": "111-111-1111",
        "emailAddress": "***@gmail.com",
        "givenName": "Test",
        "familyName": "Test",
        "phoneticGivenName": null,
        "phoneticFamilyName": null,
        "addressLines": [
            "Adress"
        ],
        "subLocality": null,
        "locality": null,
        "postalCode": "123456",
        "subAdministrativeArea": null,
        "administrativeArea": "Dummy",
        "country": "United States",
        "countryCode": "US"
    },
    "billingContact": {
        "phoneNumber": "111-111-1111",
        "emailAddress": "***@gmail.com",
        "givenName": "Test",
        "familyName": "Test",
        "phoneticGivenName": null,
        "phoneticFamilyName": null,
        "addressLines": [
            "Adress"
        ],
        "subLocality": null,
        "locality": null,
        "postalCode": "123456",
        "subAdministrativeArea": null,
        "administrativeArea": "Dummy",
        "country": "United States",
        "countryCode": "US"
    },
    "shippingMethods": [],
    "countryCode": "US",
    "currencyCode": "USD",
    "total": {
        "label": "Hello",
        "amount": "23"
    }
}

this.session = new ApplePaySession(3, request1);

There is no issue to ApplePay session and things seems to be working. I am using Java as back end and the country ISO is a String. I am struggling to understand why the Json data coming from Ajax call is causing issue while same data in hard coded in the Javascript seems good to Apple Pay
