来自webhook的无效响应:未能将JSON转换为ExecuteHttpResponse

Question

我有一个webhook从我的谷歌助理新动作生成器平台。Webhook代码是在。net vs2019中编写的。下面的链接提供了webhook请求和响应格式以及示例json。

https://developers.google.com/assistant/conversational/reference/rest/v1/TopLevel/fulfill用户https://developers.google.com/assistant/conversational/webhooks request-json_1

但是当我测试助手动作时，它失败了。下面是来自google assistant测试模拟器日志的请求和响应json。错误信息显示:无效响应来自webhook:未能将JSON转换为ExecuteHttpResponse."我不知道为什么它无效。有人能帮我解决这个问题吗?

确保您的代码返回的响应是json通过检查与筛选器，这似乎检查(即ResponseJson{}内的一切)请参阅我在https://stackoverflow.com/a/66512370/10537202上对类似问题的回应，以使用webhook游乐场。
