안녕하세요! 무신사 실시간 랭킹 크롤링 한 데이터를 mongoDB에 넣어주고 싶습니다.

그런데 해당 오류가 발생하네요 왜 그런걸까요?

client = MongoClient('mongodb+srv://test:sparta@cluster0.rfofzeu.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta
url = 'https://www.musinsa.com/ranking/best'

response = requests.get(url)

if response.status_code == 200:
    html = response.text
    soup = BeautifulSoup(html, 'html.parser')
    ul = soup.select_one('#goodsRankList')
    titles = ul.select('p.item_title > a')

    image = ul.select('div.li_inner > div.list_img > a > img')
    comment = ul.select('p.list_info > a')


    # for i, title in enumerate(titles):
