我的nodejs应用程序在我的本地没有serverless的情况下工作得很好。但是当我使用serverless.yml配置部署相同的应用程序时，我得到了这个错误“内部服务器错误”。我试图在我的s3bucket中上传文件。我不确定我在我的serverless中是否缺少任何权限相关的代码。请帮助。
我的serverless.yml

处理程序. js代码

'use strict';
const app = require('./bin/www');
const serverless = require('serverless-http');
module.exports.handler = serverless(app);

www.js码

var app = require('../app');
var debug = require('debug')('fileuploader:server');
var http = require('http');

var port = normalizePort(process.env.PORT || '80');
app.set('port', port);

var server = http.createServer(app);

server.listen(port);
server.on('error', onError);
server.on('listening', onListening);

function normalizePort(val) {
  var port = parseInt(val, 10);

  if (isNaN(port)) {
    // named pipe
    return val;
  }

  if (port >= 0) {
    // port number
    return port;
  }

  return false;
}

function onError(error) {
  if (error.syscall !== 'listen') {
    throw error;
  }

  var bind = typeof port === 'string'
    ? 'Pipe ' + port
    : 'Port ' + port;

  switch (error.code) {
    case 'EACCES':
      console.error(bind + ' requires elevated privileges');
      process.exit(1);
      break;
    case 'EADDRINUSE':
      console.error(bind + ' is already in use');
      process.exit(1);
      break;
    default:
      throw error;
  }
}

  var addr = server.address();
  var bind = typeof addr === 'string'
