django server error (500) when DEBUG=False-CodePudding

This is base.py file

from pathlib import Path

BASE_DIR = Path(__file__).resolve().parent.parent.parent


SECRET_KEY = 'h@1l- Holla!!! this is something crazy, $2423$#@$#@E@e#R3\e['

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = True

ALLOWED_HOSTS = []


INSTALLED_APPS = [
    # typical django code...

MIDDLEWARE = [
    # typical django code...
]

ROOT_URLCONF = 'project.urls'

TEMPLATES = [
    # typical django code...
]

WSGI_APPLICATION = 'project.wsgi.application'

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

AUTH_PASSWORD_VALIDATORS = [
    # typical django code...
]

STATIC_URL = '/static/'

# Static settings
STATICFILES_DIRS = [
    BASE_DIR / 'static',
]


# Media settings
MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR / 'media'


DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'

This is production.py

from .base import *

import environ
import django_heroku

env = environ.Env(
    DEBUG=(bool, False),
)

SECRET_KEY = 'lol'

# right now for convenience I've hard-coded these
# despite having environ package
DEBUG = False
ALLOWED_HOSTS = ['*']

MIDDLEWARE.insert(1, 'whitenoise.middleware.WhiteNoiseMiddleware')

DATABASES['default']['CONN_MAX_AGE'] = 60

STATIC_ROOT = BASE_DIR / 'staticfiles'

STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage'

# Activate Django-Heroku.
django_heroku.settings(locals())

I've renamed the original settings.py to base.py, and extended it to production.py. And also updated manage.py, wsgi.py and asgi.py.
Basically following this approach -> https://simpleisbetterthancomplex.com/tips/2017/07/03/django-tip-20-working-with-multiple-settings-modules.html

Everything looks just fine to me

screen shot of terminal - request error 500

This code is giving Server Error (500).
The problem is not in ALLOWED_HOSTS, that's for sure.

EDIT: few errors get fixed when I removed this line django_heroku.settings(locals()), though media files were still not loaded

Many people are facing the same problem and didn't get an appropriate answer yet!

Please help me with an answer with an explanation.
