Help! I’m stuck with a Puppeteer issue

I’m trying to visit a website using Puppeteer, but I keep encountering an error. Below is the sample code I’ve written:

const puppeteer = require('puppeteer');

async function browsePage() {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  page.on('response', res => console.log(res.request().url()));
  page.on('error', err => console.error(err.message));
  await page.goto('https://example-airline.com');
  await browser.close();
}

browsePage();

When I execute it, I receive this error message:

UnhandledPromiseRejectionWarning: Error: net::ERR_EMPTY_RESPONSE at https://example-airline.com

Oddly, the website loads normally in a standard browser, taking roughly 5-7 seconds and initiating about 135 requests. I’m curious if this issue is caused by Puppeteer, the browser engine, or some overlooked detail.

I’m running Puppeteer 1.10.0 on macOS High Sierra with Node.js 10.13. Any insights on why this might be happening? I’m really at a loss.

I encountered a similar issue when working on a project for a client. The solution that worked for me was to implement a retry mechanism with exponential backoff. This approach helps handle temporary network glitches or server-side issues. Additionally, I found that setting the ‘waitUntil’ option to ‘networkidle0’ in the page.goto() method can be beneficial. It ensures that the page is considered loaded when there are no more than 0 network connections for at least 500 ms. Here’s a snippet that illustrates these modifications:

await page.goto('https://example-airline.com', {
  waitUntil: 'networkidle0',
  timeout: 60000
});

If the problem persists, you might want to investigate if the website is using any techniques to detect and block automated browsers. In such cases, you may need to explore more advanced solutions like using a proxy or mimicking human-like behavior in your script.

hey mate, i ran into this too. try setting a longer timeout and maybe use headless: false. also check ur network, sometimes it’s just slow connection. if that don’t work, the site might have some anti-scraping stuff goin on. good luck!

I’ve experienced similar issues with Puppeteer before and have found that such errors often result from the website requiring additional handling beyond what the default settings provide. In my case, the problem was resolved by increasing the timeout value, launching Puppeteer in non-headless mode, and changing the user agent to mimic a standard browser. Additionally, ensuring JavaScript was enabled contributed to a successful load. If these adjustments don’t help, it might indicate that the website has specific security measures in place, such as anti-bot protections that require further troubleshooting.
