Can't get member count and daily post count in a Facebook group using puppeteer

Question

Been trying to get the member count and daily post count of different Facebook groups. Kept getting null or TypeError. Got those query selectors when I copied the selector from chrome.

const puppeteer = require('puppeteer')
const fs = require('fs')

// get the amount of members
const start = async () => {
    const browser = await puppeteer.launch()
    const page = await browser.newPage()
    await page.goto('https://www.facebook.com/groups/free.code.camp.world')
    const memberCount = await page.evaluate(() => {
        return document.querySelector("#mount_0_0_Hj > div > div:nth-child(1) > div > div.rq0escxv.l9j0dhe7.du4w35lb > div > div > div.j83agx80.cbu4d94t.d6urw2fd.dp1hu0rb.l9j0dhe7.du4w35lb > div.l9j0dhe7.dp1hu0rb.cbu4d94t.j83agx80 > div:nth-child(1) > div.rq0escxv.l9j0dhe7.du4w35lb.j83agx80.pfnyh3mw.taijpn5t.gs1a9yip.owycx6da.btwxx1t3.ihqw7lf3.cddn0xzi > div > div > div > div > div:nth-child(1) > div > div > div > div > div > div:nth-child(2) > span > div > div:nth-child(3) > a").textContent
    })

    // get the amount of daily posts
    const dailyPost = await page.evaluate(() => {
        return document.querySelector("#mount_0_0_Hj > div > div:nth-child(1) > div > div.rq0escxv.l9j0dhe7.du4w35lb" +
            " > div > div > div.j83agx80.cbu4d94t.d6urw2fd.dp1hu0rb.l9j0dhe7.du4w35lb >" +
            " div.l9j0dhe7.dp1hu0rb.cbu4d94t.j83agx80 > div.j83agx80.cbu4d94t.buofh1pr > div > div:nth-child(2) >" +
            " div > div > div > div:nth-child(3) > div > div > div > div > div > div:nth-child(2) > div >" +
            " div:nth-child(1) > div > div > div.rq0escxv.l9j0dhe7.du4w35lb.j83agx80.cbu4d94t.d2edcug0.hpfvmrgz.rj1gh0hx.buofh1pr.g5gj957u.o8rfisnq.p8fzw8mz.pcp91wgn.iuny7tx3.ipjc6fyt > div > div:nth-child(1) > span").textContent
    })

    console.log(memberCount)
    console.log(dailyPost)
    await browser.close()
}

start()
