node.js - google-play-billing-validator：回馈：'无效响应，请检查 \'Verifier\' 配置或上面的 statusCode'

Question

似乎在尝试使用 npm 包确认收据时，我收到了错误消息：

{ isSuccessful: false,
  errorCode: 400,
  errorMessage:
   'Invalid response, please check \'Verifier\' configuration or the statusCode above' }

我正在传递数据，如下所述：

{
        packageName: packageName,
        productId: productId,
        purchaseToken: purchaseToken,
        developerPayload: 'Acknowledged Purchase Successfully'
    }

我面临链接中提到的相同问题：https ://github.com/Deishelon/google-play-billing-validator/issues/14

任何帮助将不胜感激
