Page not loading properly with Puppeteer automation

I’m having trouble getting Puppeteer to properly load a webpage. When I try to navigate to a specific URL, the browser doesn’t seem to finish loading the page and gets stuck. The script never completes because the browser won’t close automatically.

Here’s what I’m trying to do:

const puppeteer = require('puppeteer');

(async () => {
  const browserInstance = await puppeteer.launch();
  const newPage = await browserInstance.newPage();
  newPage.on('request', (requestData) => console.log(requestData));
  newPage.on('requestfailed', (failedData) => console.log(failedData));
  newPage.on('requestfinished', (finishedData) => console.log(finishedData));
  await newPage.goto('https://example-site.com/test-page.html');

  await browserInstance.close();
})();

The problem is that none of the request events are being triggered. The request, requestfailed, and requestfinished listeners don’t fire at all.

Has anyone encountered this issue before? What could be preventing the page from loading completely?

sounds like a waitUntil problem. try { waitUntil: 'domcontentloaded' } instead of waiting for all network requests. some sites have tracking scripts that never finish loading - that’s probably what’s causing this. also test if the site works in regular chrome first. it might be blocking headless browsers completely.

Had this exact same problem last month. Your event listeners are getting attached after the page starts loading. Move them before the goto call - they need to be registered before navigation starts, not after. Also test if the URL actually works by hitting it manually first. Sometimes pages load but get stuck in infinite redirects or have JS errors that prevent completion. Try adding await newPage.setJavaScriptEnabled(false) temporarily to see if it’s a JS-related hang. Check your network connection too - slow or unstable connections cause partial loads that hang forever.

I’ve encountered this issue with pages that require authentication or specific headers. The page may be loading but getting stuck on a resource that fails to resolve. Consider adding a timeout to your goto method: await newPage.goto('https://example-site.com/test-page.html', { waitUntil: 'networkidle2', timeout: 30000 });. Additionally, set a user agent, as some sites block headless browsers. I usually add await newPage.setUserAgent('Mozilla/5.0...') before navigation to resolve hanging issues. If problems persist, launch with { headless: false } to observe the loading process.
