Passing no-sandbox but still getting error 'Running as root without --no-sandbox is not supported.`

Question

I was able to get it working using the node user and setting up a sandbox using --cap-add=SYS_ADMIN but AWS ECS Fargate does not support adding SYS_ADMIN as a linux parameter. Therefore, I am trying to pass no--sandbox to puppeteer so I can run as root but am still getting the error Running as root without --no-sandbox is not supported.

Environment

• Puppeteer version: 1.20.0
• Platform / OS version: Docker/Debian 9.12
• Node.js version: 10.21

Steps to reproduce

If I exec into the Docker container and explicitly run node puppeteer.js I do not get the error but if I make a request to my container via Postman (http://localhost:8081) I get the error.

Dockerfile

Puppeteer.js

const puppeteer = require('puppeteer');

/**
 * Initializes and returns a puppeteer instance
 * @name {getPuppeteerInstance}
 * @returns {Promise} resolves with puppeteer instance
 */
module.exports = async () => {
  try {
    const options = {
      headless: true,
      args: ['--no-sandbox', '--disable-setuid-sandbox'],
      defaultViewport: {
        width: 1440,
        height: 900,
      },
      timeout: 0,  // 0ms timeout is no timeout 
    };
    const browser = await puppeteer.launch(options);
    const page = await browser.newPage(); ``

    page.setDefaultTimeout(0);
    page.setDefaultNavigationTimeout(0);

    return { browser, page };
  } catch (error) {
    console.log(`error`, error);

    return {};
  }
};

What is the expected result? By passing --no-sandbox I would expect that would be able to launch puppeteer as root without setting up a sandbox with no issues.

What happens instead?
