  const data = await page.evaluate(() => {
    const items = document.querySelectorAll('.product');

  const browser = await puppeteer.launch({ headless: false });
  const page = await browser.newPage();

  // Fill form fields
  for (const [selector, value] of Object.entries(formData)) {
    await page.type(selector, value);
