模拟器报错UnparseableJsonResponse ("Cannot find field.")

Question

我已在 DialogFlow 控制台中使用我的 webhook 成功测试了我的应用程序的前几个意图，但在模拟器中进行测试时出现以下错误：

UnparseableJsonResponse API Version 2: Failed to parse JSON response string with 'INVALID_ARGUMENT' error: ": Cannot find field.".

注意！！！首先要注意的是它指的是"API Version 2".

没有请求到达我的 webhook - 所以看起来这一切都在 Google。

使用 Chrome 开发者工具，我看到网络条目得到了这个错误响应——一些细节如下：

从模拟器请求 url：https://assistant.clients6.google.com/v1/assistant:converse?alt=json&key=A.....

注意！！！（注意它说 'v1'）

请求负载：

{"conversationToken":"","debugLevel":1,"inputType":"KEYBOARD","locale":"en-US","mockLocation":{"city":"Mountain View","coordinates":{"latitude":37.421980615353675,"longitude":-122.08419799804688},"formattedAddress":"Googleplex, Mountain View, CA 94043, United States","zipCode":"94043"},"query":"Talk to ","surface":"PHONE"}

            }]
        }]
    },
    "visualResponse": {}
}

Google 支持人员通知我，我确实在使用版本 V2 - 我在 2017 年 12 月启动了这个 - 在 2017 年 5 月 "cutoff date" 之后很久，V2 应该是默认版本。

这是 Google 错误吗？我错过了一些设置我的意图的东西吗？或者是否有其他设置可能导致此问题？

我看到 DialogFlow 论坛中的其他帖子显示了同样的问题。

感谢任何帮助。

验证错误选项卡的内容：无法解析的JsonResponse API 版本 2：无法解析 JSON 响应字符串 'INVALID_ARGUMENT' 错误：“：找不到字段。”。

2018 年 1 月 10 日添加了欢迎意图的屏幕截图：

Answer 1

问题是两件事的结合：

响应部分中没有设置文本回复。
当 Intent 被触发时，它不会被发送到 webhook。

因此，Dialogflow 回复助手时没有文本响应，这是一个错误。

您可以通过确保您的欢迎意图执行以下操作之一来更正此问题（您不必同时执行这两项操作）：

设置一个或多个文本回复。这些将在调用 Intent 时发回。
选中 Fulfillment 下的 Use webhook 框。这会在 Intent 被触发时调用您的 webhook。（然后确保您的 webhook returns 有效响应。）

正如您在评论中推测的那样，您还可以将 Welcome Intent 更改为您已经测试响应的其他 Intent 之一。这个特殊的欢迎意向没有什么特别之处 - 它只是默认为您创建的。
