How do I handle page navigation errors in Puppeteer?

Handling page navigation errors in Puppeteer involves monitoring for errors and implementing appropriate error handling logic. Here's a detailed explanation of how to handle page navigation errors in Puppeteer: 1. Launching a new browser instance and creating a new page:

   const puppeteer = require('puppeteer');

   (async () => {
     const browser = await puppeteer.launch();
     const page = await browser.newPage();

     // Perform actions with the page here

     // Close the browser
     await browser.close();
   })();

This code sets up a basic Puppeteer script. It launches a new headless browser instance and creates a new page to work with. 2. Handling page navigation errors usingpage.on('pageerror'): Puppeteer provides an event listener calledpage.on('pageerror') that allows you to handle page navigation errors. - Handling page navigation errors:

     page.on('pageerror', (err) => {
       console.error('Page error:', err);
       // Implement error handling logic here
     });

     await page.goto('https://example.com');

In this example, thepage.on('pageerror') event listener is set up to capture any page navigation errors. When an error occurs, the error message is logged to the console usingconsole.error(). You can implement custom error handling logic within the event listener to handle the specific error scenario. 3. Handling navigation errors usingpage.on('error'): Additionally, Puppeteer provides another event listener calledpage.on('error') to handle JavaScript execution errors on the page. - Handling JavaScript execution errors:

     page.on('error', (err) => {
       console.error('JavaScript error:', err);
       // Implement error handling logic here
     });

     await page.goto('https://example.com');

In this example, thepage.on('error') event listener captures JavaScript execution errors on the page. When an error occurs, the error message is logged to the console, and you can implement your custom error handling logic. By implementing these event listeners, you can handle page navigation errors and JavaScript execution errors in Puppeteer. These listeners allow you to capture and handle errors that occur during page navigation or JavaScript execution, enabling you to implement appropriate error handling logic specific to your use case. This functionality is useful for ensuring the robustness and stability of your Puppeteer scripts by gracefully handling navigation errors and capturing any JavaScript errors that may occur during page interactions.
