저는 미국에있어서 싱가폴 AWS설정안하고 미국으로 했는데, 그래서 다른진 모르겠는데 아래 connection sting이 다릅니다. 이것때문에 DB 테스트 저장하는데 문제 발생하는걸까요?

*강의 connection string*

*제것 connection string*

mongodb+srv://test:<password>@cluster0.40l6j6u.mongodb.net/?retryWrites=true&w=majority

*강의 보고 바꾼것*

-password바꾸고 Cluster0를 ?앞에 넣음

mongodb+srv://test:sparta@cluster0.40l6j6u.mongodb.net/Cluster0?retryWrites=true&w=majority

*강의 기본코드*

from pymongo import MongoClient
client = MongoClient('여기에 URL 입력')
db = client.dbsparta

*url 복붙해서 넣은 테스트*

from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:sparta@cluster0.40l6j6u.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

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

db.users.insert_one(doc)

*결과-에러*
