Amazon Lambda / API Gateway / Amazon Lex - Error: Handled

Question

我创建了一个链接到我的 Amazon Lex 机器人的 API 网关。它在过去有效，但由于某种原因，它现在显示此错误消息。当我在 Lex 的 'Test Chatbot' 功能中测试它时，该机器人工作。

我将新函数设置为'Lambda initialization and validation.'

后出现错误

错误信息：

API:

var AWS = require('aws-sdk');
AWS.config.update({region: 'us-east-1'});

var lexruntime = new AWS.LexRuntime();

function main(event) {
  var params = {
    botAlias: 'myBot',
    botName: 'myBot',
    inputText: event.body.inputText, 
    userId: 'myUserId'

  };
  return new Promise((resolve, reject) => {
    lexruntime.postText(params, function(err, data) {
      if (err) { 
        var err2 = err.errorMessage
        reject(err2)
      }
      else {     
        resolve({data})
      }
    });
  });
}

exports.handler = main;

我在错误消息出现之前创建的新函数：

'use strict';

function close(sessionAttributes, intentName, slots, slotToElicit, message) {
    return {
        sessionAttributes,
        dialogAction: {
            type: 'ElicitSlot',
            intentName: intentName,
            slots,
            slotToElicit,
            message,
        },
    };
}

function delegate(sessionAttributes, slots){
    return { 
        sessionAttributes: sessionAttributes,
        dialogAction: {
            type: "Delegate",
            slots: slots
        }    
    };
}

function dispatch(intentRequest, callback) {
    const sessionAttributes = intentRequest.sessionAttributes;
    if(!sessionAttributes.userStatus){
        var param1 = {
            Email: null
        };
        intentRequest.currentIntent.slots = param1;
        callback(close(sessionAttributes, 'Verify', intentRequest.currentIntent.slots, 'Email', { "contentType": "PlainText", "content": "Please enter your email"}));
    }
    else {
        callback(delegate(sessionAttributes, intentRequest.currentIntent.slots));
    }
}

exports.handler = (event, context, callback) => {
    try {
        dispatch(event,
            (response) => {
                callback(null, response);
            });
    } catch (err) {
        callback(err);
    }
};

错误是什么意思？

Answer 1

我发现了问题：

固定：

function dispatch(intentRequest, callback) {
    var sessionAttributes = intentRequest.sessionAttributes;
    if(sessionAttributes){
        if(sessionAttributes.userStatus){
            callback(delegate(sessionAttributes, intentRequest.currentIntent.slots));
        }
    }
    else {
        var param1 = {
            Email: null
        };
        intentRequest.currentIntent.slots = param1;
        callback(close(sessionAttributes, 'Verify', intentRequest.currentIntent.slots, 'Email'));
    }
}
