I'm trying to build code to Web-Scrape my school website and im only in the first trying out stage and im following a tutorial.

const puppeteer = require('puppeteer');

async function scrapeProduct(url) {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto(url);

    const[el] = await page.$x('//*[@id="post-7577"]/div/div[2]/table[8]/tbody/tr[2]/td[1]');
    const td = await el.getProperty('td');
    const tdTxt = await td.jsonValue();

    console.log({tdTxt});
    console.log({td});

    browser.close();
}

scrapeProduct('https://www.gym-kahla.de/klassen-uebersicht/')

this is the code i've copied from the tutorial and placed my own link and xPath in.

the output in the console after running the file is:

$ node scrapers.js
{ srcTxt: undefined }

which confuses me because whilst the variable ''srcTxt'' was in the tutorial, its not in this changed code anymore is it?

if it helps, here the code (that worked as it did in the video) that i had ran in the same file before:

const puppeteer = require('puppeteer');

async function scrapeProduct(url) {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto(url);

    const[el] = await page.$x('//*[@id="imgBlkFront"]');
    const src = await el.getProperty('src');
    const srcTxt = await src.jsonValue();

    console.log({srcTxt});
}

scrapeProduct('https://www.amazon.com/Black-Swan-Improbable-Robustness-Fragility/dp/081297381X/ref=sr_1_1?keywords=black+swan+book&qid=1640288170&sprefix=black+swan+%2Caps%2C173&sr=8-1')

next problem, this doesn't work anymore either if i try to run it now.

i honestly have no idea what even to ask so i hoping its such a noob mistake that someone of you all will be able to find out what's going on either way.

ps: this is my first stackoverflow post so please excuse if i wrote to much in the beginning, not the right stuff or didn't respect some etiquette
