How to deploy on Heroku?

[Atiya-Rabbi]

• django-private-chat version: 0.3.0
• Django version: 2.2.13
• Python version: 3.7.2
• Operating System: Windows 8

Description

I am trying to deploy my Django app to heroku. I have deployed one instance of the app that runs via web: gunicorn dukaan.wsgi --log-file - and the other instance of the app that runs via web: python manage.py run_chat_server. There's no problem with the first instance but other instance i.e. the chat server is not working properly. Please see hereoku logs below.
It will be so kind if someone can help me to resolve this error.
