Почему flask преобразует целочисленные ключи в ответ JSON [дубликат] ⇐ Python

[Anonymous]

Почему flask преобразует в строку целочисленные ключи в этом ответе JSON?
app.py
from flask import Flask

app = Flask(__name__)

@app.route('/test', methods=['GET'])
def test_endpoint():
return {1: "test"}, 200

if __name__ == '__main__':
app.run(debug=True)

test_app.py
import pytest
from app import app

@pytest.fixture
def client():
app.config['TESTING'] = True
with app.test_client() as client:
yield client

def test_test_endpoint(client):
response = client.get('/test')
assert response.status_code == 200
assert response.json == {1: "test"}

Это завершится ошибкой
