mongoDB 연결 중 자꾸 오류가 나옵니다ㅜ

처음엔 SSL:CERTIFICATE_VERIFY_FAILED ~~ 와 같은 오류가 나와

인터프리터에서 certifi 패키지를 설치 하고

import certifi

ca=certifi.where()

tlsCAFile=ca

코드 추가해서 다시 실행하니 다른 형식의 오류가 나오네요..ㅠ_ㅠ

작성한 코드 및 에러 메세지

from pymongo import MongoClient
import certifi

ca = certifi.where()

client = MongoClient('mongodb+srv://test:<sparta>@cluster0.qumtq43.mongodb.net/?retryWrites=true&w=majority', tlsCAFile=ca)
db = client.dbsparta

doc = {
    'name' : 'bob',
    'age' : 27
}

db.users.insert_one(doc)
