Answer 1

try to close the browser before sending the response

var puppeteer = require('puppeteer');
var express = require('express');
var router = express.Router();

router.get('/', function(req, res, next) {
    (async () => {
        headless = true;
        const browser = await puppeteer.launch({headless: true});
        const page = await browser.newPage();
        url = req.query.url;
        await page.goto(url);
        let bodyHTML = await page.evaluate(() => document.body.innerHTML);
        await browser.close();
        res.send(bodyHTML);
    })();
});
