Background: I have this code working in AWS linux AMI with node 8 for lambda. Since Amazon has discontinued node 8 in lambda I have been working on transitioning to node 10 which now uses the Amazon linux 2. Since upgrading I have been unable to get past the error: socket hang up issue.

Version sets

  • Node v10.18.1
  • chrome-aws-lambda 2.0.2
  • puppeteer 2.0.0
  • Amazon Linux release 2 (Karoo)

Snippet of code:

console.log('start 1')
try {
        // create the browser session and page. Then go to url 
        const browser = await puppeteer.launch({
            // devtools: true
            args: chrome.args,
            defaultViewport: chrome.defaultViewport,
            executablePath: await chrome.executablePath,
            headless: chrome.headless,   
        })

        console.log('start 2')

        const page = await browser.newPage()

        console.log('starting browser logic')

        // set page timeout out milisecods, currently 2
        page.setDefaultTimeout(pageTimeOut)

        // goes to webpage waits for network traffic to die off
        const [startPage] = await Promise.all([
            page.goto(url),
            page.waitForNavigation({waitUntil: "networkidle0"})
        ])

Error: The Error occurs at await puppeteer.launch
