使用Google Transactions API和Google动作Java SDK的MalformedResponse

Question

我正在尝试将Google Transactions API应用于我们正在开发的演示中，但是我一直无法获得响应：textPayload：“ MalformedResponse：由于无效的平台响应，未能将Dialogflow响应解析为AppResponse：试图解析数据从系统意图出发，却失败了”，尽管考虑到我使用了Google SDK上的操作，并试图遵循文档和参考（尽管质量很差）。

以下是我从日志中获得的信息

textPayload: "MalformedResponse: Failed to parse Dialogflow response into AppResponse because of invalid platform response: Tried to parse data from system intent but failed
