dialogflow-es - 当 followupEventInput 有参数时，Dialogflow Google Assisant 中断

问题描述

我使用 Google Dialogflow 和 webhook 成功创建了一个简单的聊天机器人。该机器人要求用户输入他们的年龄。

如果他们的年龄在 18 到 60 岁之间，则 webhook 会发回“followupEventInput”响应并调用“ask_gender”事件。响应还设置了“年龄”参数。
如果年龄不在该范围内，它将调用位于另一个意图上的事件“reenter_age”并要求用户重新输入他们的年龄。这里没有设置参数。

这一切都 100% 在 Facebook 和 Dialogflow 测试窗口上运行，完全没有问题。

然后，我使用相同的意图、相同的响应等在完全相同的项目上启用了 Google Assistant。

要求用户输入他们的年龄。然后我输入一个超出预期范围的年龄，并触发“reenter_age”事件。然后，Google 助理会要求用户重新输入他们的年龄。都很好，完全没有问题。工作方式与上面相同，使用相同的代码等。
然后我输入正确的年龄，我的 webhook 发送一个“followupEventInput”响应并调用“ask_gender”事件。响应还设置了“年龄”参数。与上述第一点完全相同。但是，不幸的是，我不断收到带有代码 14 的“Webhook 错误 (206)”响应。在这里，Google 助理应该询问此人的性别（这个问题来自与被调用事件相关联的意图，而不是来自我的 webhook），但这不会发生（在 Facebook 和右侧的 Dialogflow 测试窗口中完美运行）。

当我从我的响应中删除参数值时，谷歌助手将继续询问参数提示，因为参数值永远不会被设置，这是正确的，这是应该发生的。

我确实相信这可能是一个错误，但如果您也偶然发现这一点，我将非常感谢您的意见。

这会显示在 Google 助理模拟器窗口中：“抱歉，COMPANY_NAME 封面现在没有响应。请稍后再试。” 就在“xxx已经离开对话”的下方。

有趣的是，在“音频”选项卡中显示了助手应该问的文本：“谢谢。你是男性还是女性？”

以下是来自 Google Assistant 模拟器测试页面的调试日志：
