I have a NodeJS Typescript project, and I am trying to get all the 'p' tags from a dynamically rendered website (not STATIC HTML but instead makes multiple requests to backend to get some data and render webpage). I am using typescript and have ["es6", "dom"] in my lib, and I have the following code (this is all my code in the project so far):

import puppeteer from 'puppeteer';

const getLinks = async () => {
    const browser = await puppeteer.launch();
    const [page] = await browser.pages();

    await page.goto('https://webscraper.io/test-sites', { waitUntil: 'networkidle0' });
    const links = await page.evaluate(() => document.querySelectorAll('p'));
    console.log(links);
    await browser.close();
}

However, I keep getting undefined when I print links. I assume this is because the program can't find any 'p' tags. Why is this?

Note: the url provided is just an example. I have tried across multiple different sites and I still get undefined.

Any help is appreciated! Thanks!
