如何在自动驾驶仪 Twilio 中重置流程？
How can I reset a flow in autopilot Twilio?
我正在尝试取消或重置流程，同时响应收集问题，如果客户选择了一个错误的选项并且他想取消，这是必要的，但现在我只是退出收集添加验证收集和何时完成 max_attempts，我重定向到 main.
我想写 CANCEL 并重定向到 Main，我尝试了一个函数，但收集验证不允许我将重定向从函数发送到 Main Task。
有什么想法吗？
非常感谢。
这是我的功能：
exports.handler = function(context, event, callback) {
var got = require('got');
var value = event.CurrentInput;
if(true){
let responseObject = {
"actions": [
{
"redirect": "task://greetings"
}]
};
callback(null, responseObject);
}};
后来我在 webhook 中使用 onCollectAttempt 调用它，但它没有发生任何事情，只是继续 Collect
Function
Webhook

由于 Collect 函数的当前 JSON bin 不允许“取消”或 "resetting"，因此没有简单的方法来执行此操作，但这是一个潜在的与动态 Collect 一起使用的变通方法（您使用 Twilio Function 将其写入 Node.js 而不是将其写入 Autopilot 控制台的 JSON bin。
下面我们有：
1. 我们需要的 Collect 问题集（要涵盖来自单个函数的许多收集，我们需要一些额外的东西，比如动态地从 db/passing 中提取它们）
2. 我们可以使用静态单词检查的用例的代理关键字，例如指示用户随时键入 "agent" 以定向到人类。
