serverless-plugin: ECONNREFUSED

@adieuadieu Thanks for starting such an awesome project. I’m trying to follow the README for the project’s serverless plugin, but found that the steps documented did not work for me.

Here’s what I’ve tried.

package.json

{
  "name": "serverless-chrome-plugin",
  "version": "0.0.1",
  "description": "hello, does it work?",
  "main": "index.js",
  "scripts": {
    "deploy": "serverless deploy -v"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "chrome-remote-interface": "0.24.5"
  },
  "devDependencies": {
    "serverless": "1.21.0",
    "serverless-plugin-chrome": "1.0.0-11"
  }
}

serverless.yml

service: hello-serverless-chrome-plugin

frameworkVersion: "1.21.0"
provider:
  name: aws
  runtime: nodejs6.10
  region: us-west-2
  stage: dev
  profile: lithiumdev 

plugins:
  - serverless-plugin-chrome

functions:
  hello:
    handler: handler.hello
    description: try out this ol' lambda thing
    memorySize: 1536
    timeout: 60

    events:
      - http:
          path: hello
          method: get

handler.js

const CDP = require('chrome-remote-interface')

module.exports.hello = (event, context, callback, chrome) => {
  // Chrome is already running!

  CDP.Version()
    .then((versionInfo) => {
      callback(null, {
        statusCode: 200,
        body: JSON.stringify({
          versionInfo,
          chrome,
        }),
      })
    })
    .catch((error) => {
      callback(null, {
        statusCode: 500,
        body: JSON.stringify({
          error,
        }),
      })
    })
}

When I invoke on lambda, I get this response: {"error":{"code":"ECONNREFUSED","errno":"ECONNREFUSED","syscall":"connect","address":"127.0.0.1","port":9222}}

I’m a bit new to both node and CDP. I was wondering, could you suggest what might be going wrong?

Hi,

I have a similar issue, I am getting: “errorMessage”: “connect ECONNREFUSED 127.0.0.1:9222”, “errorType”: “Error”, “stackTrace”: [ “Object.exports._errnoException (util.js:1018:11)”, “exports._exceptionWithHostPort (util.js:1041:20)”, “TCPConnectWrap.afterConnect [as oncomplete] (net.js:1086:14)” ]

when I try to run chrome on lambda serverless. I deploy from mac.

Thanks!

We can close this ticket as soon as you confirm it works.

@carlosbaraza @adieuadieu confirmed … Once I upgraded to serverless 1.21.1, issue was resolved for me. Thanks!
