4주차 mars appy.py 와 index.html 코드 완료 후 실행하니 오류가 뜹니다.

작성한 코드 및 에러 메세지

아래가 제가 작성한 코드이고

from flask import Flask, render_template, request, jsonify
app = Flask(__name__)



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


@app.route('/')
def home():
    return render_template('index.html')


@app.route("/mars", methods=["POST"])
def mars_post():
    name_receive = request.form['name_give']
    address_receive = request.form['address_give']
    size_receive = request.form['size_give']


    doc = {'name': name_receive,
       'address': address_receive,
       'size' : size_receive
       }
    db.mars.insert_one(doc)



    return jsonify({'msg':'저장완료!'})


@app.route("/mars", methods=["GET"])
def mars_get():
    return jsonify({'msg':'GET 연결 완료!'})


if __name__ == '__main__':
    app.run('0.0.0.0', port=5000, debug=True)
