How to generate PDF after editing and removing content in the puppeteer?

Hello, I'm trying to create a pdf with specific content by editing the content returned by the puppeteer.

PDF is not generated with new content.

Could anyone help?

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('http://www. site .com');
  await page.evaluate(() => {
    let image = document.getElementsByTagName('img')[4];
        image.parentNode.removeChild( image );
    let name = document.querySelector('.name');
    name.innerHTML = 'changeName';
  });
  await page.pdf({path: 'file.pdf', format: 'A4'});
  await browser.close();
})();

Answer 1

let name = document.querySelector('.name');
        name.innerHTML = 'changeName';

to

let name = document.querySelector('.name')[3];
        name.innerHTML = 'changeName';
