Я работаю в веб-приложении Flask Python (я использую Python 3.6.8), но когда я запускаю команду "cf push" или "ibmcloud app push", программа не может запустить приложение (Ожидание приложение, чтобы начать ... Начало неудачно)

app.py:

from flask_httpauth import HTTPBasicAuth
from dotenv import load_dotenv

# Emit Bluemix deployment event
cf_deployment_tracker.track()

app = Flask(__name__)

# define basic auth
auth = HTTPBasicAuth()

# On Bluemix, get the port number from the environment variable PORT
# When running this app on the local machine, default the port to 8000
port = int(os.getenv('PORT', 8000))

Я уже внес изменение, но у меня все еще есть проблемы с загрузкой программы, 

#!/usr/bin/python3

Я понял, что теперь поменяю проблему в лог-файле
