目前，我正在验证我的链接android应用google服务帐户以验证并尝试在应用中确认android订阅。我可以使用GET调用验证它们，但当我进行POST并将:acknowledge附加到URL末尾时，我收到以下错误

{
    "error": {
        "code": 400,
        "message": "The product purchase is not owned by the user.",
        "errors": [
            {
                "message": "The product purchase is not owned by the user.",
                "domain": "androidpublisher",
                "reason": "productNotOwnedByUser"
            }
        ]
    }
}

服务帐户已被授予所有权限，因为我可以告诉通过android应用商店x1c 0d1x
当我在没有:acknowledge的情况下进行GET调用时，我会收到这样的响应，并且可以看到订阅仍然没有被确认。

当使用google-play-billing-validator节点包时，我只看到两次成功的确认购买。这发生在我第一次尝试时，然后在测试期间取消订阅后，重试，我无法再次确认。然后他们不断取消。

exports.googlePlayBillingValidator = functions.https.onRequest((request, response) => {
  // capture the data from the request
  const { purchaseObject, subscriptionID, type } = request.body;
  console.log(subscriptionID, type);
  // inclue your app bundle id
  const bundleID = "edu.fit.my.jgibb2018.pob";
  // require the service account info
  const googleServiceAccountKey = require("./pc-api-6835501382478242417-177-5781829bedc5.json"); // see docs on how to generate a service account
  // require the verify module
  const Verifier = require("google-play-billing-validator");
  // create verifier opitons object
  const options = {
    "email": googleServiceAccountKey.client_email,
    "key": googleServiceAccountKey.private_key,
  };
  // create a new verifier instance
  const verifier = new Verifier(options);
  // create a receipt object
  const receipt = {
    packageName: bundleID,
    productId: purchaseObject.productId,
    purchaseToken: purchaseObject.purchaseToken,
    
  };
  if (type.contains("subscriptionAcknowledge")) {
    // add the following string to the receipt object `developerPayload: "some unique identifier",`
    receipt.developerPayload = "some unique identifier";
  }
  // acknowledge the receipt
  const promiseData = verifier.verifySub(receipt);

  promiseData.then(function (r) {
    response.send(r);
  })
    .catch(function (error) {
      functions.logger.error(error);
      response.send(error);
    });
});
