我尝试将我的代码直接推送到Heroku进行托管，但是我遇到了很多错误 . 现在，我所做的是在Github上托管代码，然后将git repo与Heroku链接 . 现在，Heroku应用程序已成功创建，但现在它没有运行，因为它崩溃时出现错误代码H10和状态503.我的app.py代码是;

from flask import Flask

app = Flask(__name__)


@app.route('/')
def hello():
    return "Hello World"

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

来自Heroku
