receipt-data property was malformed

[WinnieS0728]

Hello,

I'm using this repo as backend, and expo-iap as frontend.

I'm now facing an error receipt-data property was malformed.

what should I pass as receipt to

$receiptResponse = Product::appStore()->receiptData($receipt)->verifyReceipt();

description

my purchase payload from expo-iap is like

{
    "originalTransactionIdentifierIOS": "xxx",
    "storefrontCountryCodeIOS": "TWN",
    "environmentIOS": "Sandbox",
    "ids": [
        "productId"
    ],
    "transactionId": "xxx",
    "productId": "productId",
    "reasonIOS": "PURCHASE",
    "quantityIOS": 1,
    "originalTransactionDateIOS": 123123,
    "webOrderLineItemIdIOS": null,
    "currencyIOS": "TWD",
    "transactionReceipt": "{\"transactionId\":\"xxx\",\"originalTransactionId\":\"xxx\",\"bundleId\":\"xxx\",\"productId\":\"xxx\",\"purchaseDate\":xxx,\"originalPurchaseDate\":xxx,\"quantity\":1,\"type\":\"Non-Renewing Subscription\",\"deviceVerification\":\"xxx\",\"deviceVerificationNonce\":\"xxx\",\"inAppOwnershipType\":\"PURCHASED\",\"signedDate\":xxx,\"environment\":\"Sandbox\",\"transactionReason\":\"PURCHASE\",\"storefront\":\"TWN\",\"storefrontId\":\"xxx\",\"price\":3990000,\"currency\":\"TWD\",\"appTransactionId\":\"xxx\"}",
    "ownershipTypeIOS": "PURCHASED",
    "id": "xxx",
    "revocationReasonIOS": null,
    "countryCodeIOS": "TWN",
    "platform": "ios",
    "transactionReasonIOS": "PURCHASE",
    "isUpgradedIOS": false,
    "purchaseToken": "JWT_token",
    "subscriptionGroupIdIOS": null,
    "priceIOS": 3990000,
    "appBundleIdIOS": "xxx",
    "revocationDateIOS": null,
    "appAccountToken": null,
    "jwsRepresentationIOS": "JWT_token",
    "expirationDateIOS": null,
    "transactionDate": 123123,
    "currencyCodeIOS": "TWD",
    "productTypeIOS": "Non-Renewing Subscription",
    "currencySymbolIOS": "NT$"
}

I try to pass transactionReceipt (the stringify JSON) or jwsRepresentationIOS (the JWT_token).
both throw this receipt-data property was malformed error.

another information, I'm using react-native-iap before.
and when using react-native-iap, it have a column like "MIIS......"
when I pass this string as receipt, it works

storekit

the "MIIS..." one is storekit 1 and apple now using storekit 2,
storekit 2 is using JWS

I don't know how to solve this.
is there any way can accept storekit2's JWS.
or should I downgrade to storekit1?
