错误“空语音响应”

我试图连接 DialogFlow 和 Actions on Google ，所以我创建了一些意图，连接了服务，添加了显式和隐式调用等，但是当我在模拟器中尝试机器人https://console.actions.google.com/project/[projectId]/simulator/它总是给我错误：

“无法将Dialogflow响应解析为AppResponse，异常抛出消息：空语音响应”

即使是艰难的inputType也是“KEYBOARD” .

到目前为止我尝试了什么：

• 我确实在Dialog Flow中设置了"Response from this tab will be sent to the Google Assistant integration"（您是否必须为每一个意图设置它？），但我没有看到任何额外的语音设置 .

• 我禁用了第二语言，首先我也用德语打算

• 我还关闭了Fullfillment Webhook（在API v1中实现，然后也在v2中实现），没有任何变化

• 我只发现这个用户有同样的问题https://productforums.google.com/forum/#!topic/dialogflow/xYjKlz31yW0;context-place=topicsearchin/dialogflow/Empty $ 20speech $ 20response但没有解析 .

• 在意图中检查履行复选框

• 当我在Dialog Flow右侧的"Try it now"或Web Demo中使用它时，机器人工作正常https://bot.dialogflow.com/994dda8b-4849-4a8a-ab24-c0cd03b5f420

不幸的是，文档没有说明这个错误 . 有任何想法吗？

这里是Actions集成错误的屏幕截图：

这是完整的调试输出：

“debugInfo”听起来像是一个内部问题：

“API Version 2：无法使用'INVALID_ARGUMENT'错误解析JSON响应字符串：\”：找不到字段 . \“ . ”

这是欢迎意图的屏幕截图：

PS . 我花了很多时间才弄清楚是什么

“自定义意图缺少查询模式”

意味着 - 所以我只是在这里记录它：在Dialog Flow中 - 意图 - “用户说”当你想将它设置为查询参数时，你必须在文本输入字段中单击一个单词 - 这似乎是Actions on谷歌 .
