连接烧瓶和远程mongo db

Question

我正在尝试使用flask和mongoDB。
我创建了一个集群和一个集合（已添加图像）。
我使用brew在本地安装mongoDB并使用brew services start mongodb-community运行它。
我正在添加python代码和尝试将get请求发送到localhost：5000时遇到的错误。

请让我知道我在做什么错。
预先感谢！

from flask import Flask
from flask import jsonify
from flask_pymongo import PyMongo

app = Flask(__name__)

app.config['MONGO_DBNAME'] = 'python_connection'
app.config[
    'MONGO_URI'] = 'mongodb+srv://myUserName:<myPassword>@cluster0-eipr0.mongodb.net/test?retryWrites=true&w=majority'
mongo = PyMongo(app)


@app.route("/")
def index():
    col = mongo.db['first_collection']
    a = col.find()[0]
    return jsonify({'result': a.name})
