Node.js 无服务器框架：未找到无服务器错误函数：

我开始使用nodejs和无服务器框架

My handler.js包含：

'use strict';
var index = require('./index.js');

module.exports.hello = async event => {
  var res = await index.main();

  console.log('hello');
  console.log(res);

  console.log('IN HANDLER');
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'main function executed!',
        input: event,
      },
      null,
      2
    ),
  };


};

my index.js：

async function main(event, context, callback) {
  const chromium = require('chrome-aws-lambda');
  const puppeteer = require('puppeteer');
  const os = require('os');
  const CREDS = require('./.creds');

  // exports.handler = async (event, context, callback) => {
  let result = null;
  let browser = null;

    try {
      browser = await chromium.puppeteer.launch({
        args: chromium.args,
        defaultViewport: chromium.defaultViewport,
        executablePath: await chromium.executablePath,
        headless: chromium.headless,

    } 
      catch {
      console.log('browser failed')
    };



  var page = await browser.newPage();

   ........



  // })().catch(e => { console.error(e) });
};

main().catch(e => { console.error(e) });

module.exports.main = main;

当我跑步时：

$ sls invoke -f hello

 Serverless Error ---------------------------------------

 Function not found: arn:aws:lambda:us-east-1:155754363046:function:sellthelandnow-dev-hello

错误在标题中。我做错了什么？让我在这里解释一下。无服务器框架可以通过两种方式（本地和云中）调用（运行）lambda。 似乎您正试图在AWS中调用lambda。（arn:aws:lambda:us-east-1:155754363046:function:sellthelandnow dev hello）基本上，此arn不存在于您的aws-155754363046帐户中。你需要使用

serverless deploy

将lamdba部署到aws env。如果您只想在本地进行测试，则命令为

serverless invoke local --function functionName

因此，我建议您在云中调用lambda，您需要首先部署它或使用invoke local

谢谢

sellthelandnow开发人员您好

？我不会在代码中的任何地方使用它。非常感谢！
