Puppeteer Infinity Scrolling is not working

[masumluf]

I’ve made a script to grab some data from a website, I have implemented infinity scroll in my script but it is only scroll only one times.I have been debugged it scroll function is triggering but it is not working, here is my code below, pagination function is triggering on time but it is not scrolling .

const puppeteer = require("puppeteer");


let page;
let finalResults = [];
let count = 0;

async function fStarMain() {
  const browser = await puppeteer.launch({ headless: true });
  page = await browser.newPage();
  //const { page } = puppeteerCore();
  await page.setViewport({ width: 1200, height: 1500 });

  await page.goto("https://fusionread.com/search-result/bitcoin_hack", {
    waitUntil: "networkidle2",
  });
  async function paginate() {
    let count = 0;
    let nextClick = await page.$(".jss85");
    console.log(nextClick);
    if (!nextClick && !count) {
      console.log(count);
      await Promise.all([
        //page.waitForSelector(".list-border li"),
        await page.waitFor(500),
        await page.evaluate("window.scrollTo(0, document.body.scrollHeight)"),
      ]);

      console.log("count increment");
      await collectData();
    } else {
      count = null;
    }

    //await page.waitFor(1000);
  }

  function printData(results) {
    // console.log("function trigggered");
    for (let value of results) {
      console.log(value);
    }
  }

  async function collectData() {
    console.log("Data collection started");
    count++;
    let results = await page.evaluate(() => {
      return [
        ...document.querySelectorAll(".infinite-scroll-component > div"),
      ].map((element) => ({
        title: element.querySelector("a").innerText,
      }));
    });
    //console.log(results);
    printData(results);
    await paginate();

    // return results;
  }
  //console.log(results);

  //console.log("recheck pagination");
  await collectData();
}

module.exports = fStarMain;
