Puppeteer Error: Protocol error (Page.captureScreenshot): Target closed

I have this error running puppeteer@1.12.2 on node:8-slim container.

The full error:

Error: Protocol error (Page.captureScreenshot): Target closed.     at Promise (/app/node_modules/puppeteer/lib/Connection.js:183:56)     at new Promise (<anonymous>)     at CDPSession.send (/app/node_modules/puppeteer/lib/Connection.js:182:12)     at Page._screenshotTask (/app/node_modules/puppeteer/lib/Page.js:903:39)     at <anonymous>     at process._tickCallback (internal/process/next_tick.js:189:7)   -- ASYNC --     at Page.<anonymous> (/app/node_modules/puppeteer/lib/helper.js:108:27)     at /app/test.js:9:15     at <anonymous>     at process._tickCallback (internal/process/next_tick.js:189:7) 

The js file (inspired by GoogleChrome/puppeteer/examples/screenshot.js):

const puppeteer = require('puppeteer'); (async() => {          const browser = await puppeteer.launch({                 headless: true,                 args: ['--no-sandbox', '--disable-setuid-sandbox', '--disable-gpu', '--disable-dev-shm-usage']          });           const page = await browser.newPage();           await page.goto('http://google.com');           await page.screenshot({path: 'example.png'});           await browser.close(); })(); 

The Dockerfile (inspired by troubleshooting.md#running-puppeteer-in-docker):

 FROM node:8-slim  RUN apt-get update && apt-get install -yq libgconf-2-4  RUN apt-get update && apt-get install -y wget --no-install-recommends /     && wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - /     && sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' /     && apt-get update /     && apt-get install -y google-chrome-unstable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst ttf-freefont /       --no-install-recommends /     && rm -rf /var/lib/apt/lists/* /     && apt-get purge --auto-remove -y curl /     && rm -rf /src/*.deb  WORKDIR /app RUN chown node: /app  user node  COPY ./ ./ RUN npm i --unsafe-perm=true  CMD ["node", "test.js"]  

The same test.js makes high quality screenshots on the host OS, but fails in a container.

Is there any magic parameter to run it in node-slim container? I am happy with any version of puppeteer that works.

Version of google-chrome-unstable installed from Dockerfile is "73.0.3683.20 dev". Version of chrome installed by npm is "73.0.3679.0".

UPDATE:

I have tried to add await page.close() as Cody G. suggested:

const puppeteer = require('puppeteer'); (async() => {          const browser = await puppeteer.launch({                 headless: true,                 args: ['--no-sandbox', '--disable-setuid-sandbox', '--disable-gpu', '--disable-dev-shm-usage']          });           const page = await browser.newPage();           await page.goto('http://google.com');           await page.screenshot({path: 'example.png'});           await page.close();           await browser.close(); })(); 

It didn't make much difference. The error is still thrown at line 9 await page.screenshot so I guess it didn't reach the added line.

UPDATE 2:

I have added event loggers like this:

const puppeteer = require('puppeteer'); (async() => {         try{          const browser = await puppeteer.launch({                 headless: true,                 args: ['--no-sandbox', '--disable-setuid-sandbox', '--disable-gpu', '--disable-dev-shm-usage']          });           const page = await browser.newPage();           const eventHandler = e=>(...args)=>console.log({e,args});           for(let e of [                   'close',                   'console',                   'dialog',                   'domcontentloaded',                   'error',                   'frameattached',                   'framedetached',                   'framenavigated',                   'load',                   'metrics',                   'pageerror',                   'popup',                   'request',                   'requestfailed',                   'requestfinished',                   'response',                   'workercreated',                   'workerdestroyed'           ]) {                 page.on(e, eventHandler(e));           };           await page.goto('http://google.com');           await page.screenshot({path: 'example.png'});           await page.close();           await browser.close();         } catch(e){                 console.error({e});         } })(); 

The full log is quite long and is available at https://gist.github.com/blex18/10ae4eed389ca818d72218baad3dfad2.

Essentially, after few redirects it landed at https://www.google.com/?gws_rd=ssl followed by resource and xhr requests.

UPDATE 3:

The package.json:

{   "name": "pup",   "version": "1.0.0",   "description": "",   "main": "index.js",   "scripts": {     "test": "echo /"Error: no test specified/" && exit 1"   },   "author": "",   "license": "ISC",   "dependencies": {     "puppeteer": "^1.12.2"   } }

Your issue is not reproducible. It works on my Centos 7, your Mac environment, so it seems to be a problem with the Docker configuration and not with the code. Possible problems:

  1. Used docker storage driver: aufs can be a problem, especially for older kernels and write/delete operations in the container; if it is possible try default overlay2
  2. Used security profiles: apparmor and seccomp are enabled, you may try to run with --security-opt seccomp=unconfined and check dmesg, maybe security is blocking something
