I’m trying to scrape all of meaning and similar word data from this site https://en.dict.naver.com/#/search?query=${variable}
[ex)https://en.dict.naver.com/#/search?query=win]
the scrape result is null

 async function web(word){
     const browser = await puppeteer.launch({headless : false});
     const page = await browser.newPage();
     await page.goto('https://en.dict.naver.com/#/search?query='+encodeURIComponent(word),{waitUntil:'networkidle0'});
  console.log('https://en.dict.naver.com/#/search?query='+encodeURIComponent(word))
  let meandata = await page.$$(".section.section_keyword .mean");
  let mean = await page.evaluate(elements => {
    return elements.map(element => element.textContent);
}, meandata);

  let sidata = await page.$$(".component_summary _thesaurusSwiper .word");
  let si = await page.evaluate(elements => {
    return elemenst.map(element => element.textContent);
}, sidata);

  await browser.close();

  const result = {min,si}
  return result;
};

    app.post('/index',whlo,async function(req,res){
  if(req.body.added){
    const word = req.body.added;
    const result = await web(word);
    console.log(result)
  })

output
https://en.dict.naver.com/#/search?query=word

{
min: [
null, null, null, null, null,
null, null, null, null, null,
null, null, null, null, null,
null, null, null, null, null,
null, null, null, null, null,
null
],

si: [
null, null, null, null,
null, null, null, null,
null, null, null, null,
null, null, null, null,
null, null, null, null,
null, null
]
}

the link is correct but the output is null
i think there may be a problem with the code let meandata = await page.$$(".mean"); or html code of that site but i dont know what is wrong although i’ve seen some similar questions in stack overflow
expect
{
min: [
이기다, (경기 등에서 이겨 무엇을) 따다[타다/차지[쟁취]하다], 승리, 근로 장려책, [타도 인플레이션] ((Gerald R. Ford 대통령 시대의 슬로건)),

si: [
