I'm trying to deploy a Python project using Django in Heroku. The deploy happens all right, but when trying to do heroku run python manage.py migrate The following error occurs.

Traceback (most recent call):

This is my configs.py file

# Default email password

# Check the port used by the email service

EMAIL_USE_TLS = True

Does anyone know what may be happening?
