我试图从对话框流中调用webhook,而不是从webhook获得响应,我从响应部分得到的响应,我已将其置于意图中 . 我还为每个意图启用了webhook,并且还放置了webhook URL,该URL是从firebase CLI在履行URL部分生成的 . 我附上了firebase日志和JSON响应的屏幕截图,我们在对话框流程“show JSON”和index.js文件中也看到了 . 我被困了2周才解决它 .

const asst = new DialogflowApp({request: req, response: res});

我刚刚遇到了这个完全相同的错误,这是因为我忘了将我的意图名称放在
Actions
部分的Enter action name
字段中 .所以,由于我没有指定一个,因此将
null
作为意图名称 .我只是通过 very carefully 重新阅读https://developers.google.com/actions/dialogflow/first-app来解决它 .
谢谢大家的宝贵回应 . 不知何故,我能够修复此null错误 . 实际上,我在代理的API版本部分启用了“Dialogflow V2 API” . 现在,我已禁用它,它对我有用 .
对于每个代理,都需要一个
unknown
Intent处理程序来处理意外情况,例如null等
