无服务器框架：未找到无服务器错误 Function：

Question

我开始使用 nodejs 和无服务器框架。

我的 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
    ),
  };


};

我的 serverless.yml 包含：

# You can pin your service to only deploy with a specific Serverless version
# Check out our docs for more details
# frameworkVersion: "=X.X.X"

provider:
  name: aws
  runtime: nodejs12.x
  region: us-east-1
  # here we put the layers we want to use
  layers:
    # Google Chrome for AWS Lambda as a layer
    # Make sure you use the latest version depending on the region
    # https://github.com/shelfio/chrome-aws-lambda-layer
    # - arn:us-east-1:arn:aws:lambda:us-east-1:764866452798:layer:chrome-aws-lambda:10
    - arn:aws:lambda:us-east-1:764866452798:layer:chrome-aws-lambda:10
  # function parameters

# you can add packaging information here
#package:
#  include:
#    - include-me.js
#    - include-me-dir/**
#  exclude:
#    - exclude-me.js
#    - exclude-me-dir/**

functions:
  hello:
    handler: handler.hello
  # main:
    # handler: handler.main
#    The following are a few example events you can configure
#    NOTE: Please make sure to change your handler code to work with those events
#    Check the event documentation for details
    events:
     - http:
         path: hello/get
         method: get

我的 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,
        ignoreHTTPSErrors: true,
      })
    } 
      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;

当我运行时：

$ 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。 我在这里做错了什么？

Answer 1

让我在这里解释一下。 无服务器框架可以通过两种方式（本地和云端-AWS）调用（运行）lambda。 您似乎正在尝试在 AWS 中调用 lambda。 （arn:aws:lambda:us-east-1:155754363046:function:sellthelandnow-dev-hello）基本上这个arn在你的AWS-155754363046账户中不存在。 你需要使用

serverless deploy

将 lamdba 部署到 aws env。如果您只想在本地测试，命令是

serverless invoke local --function functionName

所以我建议如果你想在云端调用 lambda。你需要先部署它或者你使用调用本地。

谢谢，

Answer 2

In my specific case i had this error code when i deleted the deplyed lambda function in the AWS Management Console but did not delete the Application Stack and tried to deploy the lambda function again using

serverless deploy

您必须删除应用程序堆栈，并确保删除 lambda 的 IAM 执行角色。

---

附加信息

我不必删除 s3 存储桶 - 它已被重复使用。

您可以在 AWS 管理控制台中找到您的应用程序堆栈

• AWS Management Console → Lambda → Applications

并删除

• AWS Management Console → CloudFormation → Stacks
• 如果删除失败，系统可能会提示您保留关联资源（IAM 角色和 s3 存储桶）
• 选择保留资源并在之后手动删除它们

错误信息

发生错误：[functionName]LambdaFunction - 资源处理程序返回消息：“Lambda function [应用程序堆栈名称]-[应用程序阶段]-[lambda function 名称] 找不到”（RequestToken：010100101-001-101-01 ，处理程序错误代码：未找到）。
