Как я могу запустить приложение FastAPI и бот Telegram в одном коде? ⇐ Python

[Anonymous]

У меня есть приложение Python, которое использует FastAPI для обработки веб-перехватчиков, и я пытаюсь интегрировать бота Telegram в свое приложение, но не могу запустить сервер Telegram, я пытался использовать многопоточность. Однако бот Telegram не работает, и я получаю эту ошибку

это функция запуска Telegram из класса TelegramNotification
def lunch_bot(self):
application = Application.builder().token(self.BOT_TOKEN).build()
print('Bot is running...')

# Commands
application.add_handler(CommandHandler('start', self.start))

а это мой файл index.py
