我已经创建了一个节点lambda函数,它可以对Aurora数据库进行简单的调用.当我在控制台中测试函数时,查询返回,我可以在日志中看到结果,但回调似乎永远不会被调用,所以我的lambda函数超时.我无法弄清楚问题是什么.希望有人在这里可以指出我的问题.

var mysql = require("mysql");

module.exports.handler = function(event, context, cb) {
  console.log('start\n');
  var con = mysql.createConnection({
    ...
  });
  console.log('call data\n');

  con.query('SELECT * FROM Tags', function(err, rows) {
    console.log('Data received from Db:\n');
    console.log(rows);

    console.log('calling callback');

    cb(null, 'Success');

    console.log('callback called');
  });
  console.log('data called\n');
};

生成的Cloudwatch日志如下......
