잘되다가

또..막혔어요 ㅠㅠㅠㅠㅠㅠ

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

from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:sparta@cluster0.esj3ket.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

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

@app.route("/mars", methods=["POST"])
def web_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': '주문 완료!'})

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

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

이건 app.py인데요.
