我是node.js的新手，我正在尝试使用Dialogflow构建聊天机器人，该对话框可让您计划约会并将约会插入Google日历。无论尝试如何，我似乎一直都在遇到相同的错误（没有针对请求意图的处理程序）。是否有人看到可能出了问题的内容或尝试过本教程并能正常工作？
我尝试过的事情：
这是我遵循的教程：
This是特定意图“计划约会”的屏幕截图。它会自动转到默认的响应，但应该转到：Ok, let me see if we can fit you in. ${appointmentTimeString} is fine!.此意图中包含一个自定义实体：@AppointmentType，具有2个选项：- 车辆登记-驾照
在意图屏幕截图中，您还看到时间给出了今天的日期（在这种情况下为2020-02-28），而时间应该给出了所请求的约会日期（在这种情况下为2020-03-10）。这可能会导致错误，但是我不知道如何在嵌入式编辑器中解决该问题。
我的Inline编辑器中的index.js（日历ID和服务帐户数据正确，只是从这里取出来了）：

在代理将您的请求路由到正确的功能之前，您似乎正在读取参数。尝试像这样在函数内部删除函数makeAppointment上方的那一行。
function makeAppointment (agent) { // Calculate appointment start and end datetimes (end = +1hr from start) const appointment_type = agent.parameters.AppointmentType; const dateTimeStart = new Date(Date.parse(agent.parameters.date.split('T')[0] + 'T' + agent.parameters.time + timeZoneOffset));希望这对您有用，因为其他所有东西似乎都被正确吸收了。
