Apple In-App Kaufwebhook fehlschlägt mit Status 21002 (ungültige Quittungsdaten) ⇐ IOS

[Anonymous]

Ich bearbeite iOS In-App-Kauf von Webhooks in meinem Node.js-Backend mit Express. Mein Webhook verarbeitet einmalige Einkäufe und überprüft die Transaktion mit Apple. Ich stoße jedoch auf einen "Status": 21002 Fehler bei der Überprüfung der Quittung. < /P>

const iosWebhookService = new IosWebhookService();

export const unifiedWebhookHandler = async (
req: Request,
res: Response

try {
const { signedPayload } = req.body;
console.log("reqBody: ", JSON.stringify(req.body, null, 2));

const event =

console.log("event: ", JSON.stringify(event, null, 2))
