After much research, I still can’t do it guys. My main goal is to translate a single PDF page in the free translation service in Google Translate with puppeteer in nodejs. It gave me the errors.

Here’s my code:

const puppeteer = require('puppeteer');

(async () => {
  // Launch a headless browser
  const browser = await puppeteer.launch();

  // Open a new page
  const page = await browser.newPage();

  // Replace the URL below with the URL of the PDF you want to translate
  const pdfUrl = 'https://www.cbu.edu/wp-content/uploads/2020/05/2019-20-ece-computersystems-cs.pdf';

  // Navigate to the PDF translation page
  await page.goto(`https://translate.google.com/translate?hl=en&sl=fr&u=${encodeURIComponent(pdfUrl)}`);

  // Wait for the translation page to load
  await page.waitForSelector('#contentframe iframe');

  // Get the source URL of the translated content iframe
  const iframeSrc = await page.evaluate(() => {
    return document.querySelector('#contentframe iframe').src;
  });

  console.log('Found iframe:', iframeSrc);

  // Navigate to the translated content iframe
  await page.goto(iframeSrc);

  // Wait for translation to complete
  await page.waitForTimeout(5000); // Adjust the timeout as needed based on the translation complexity

  // Print the translated content to PDF
  await page.pdf({ path: '/tmp/translated_pdf.pdf' });

  console.log('PDF translation completed successfully.');

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

Here are the errors it gave me:

How can I fix them and make this code work please? I don’t want you to just look at it and say nothing. Please, I want you all to take part in solving this problem for me…
