Heroku Bad Request Server Error 500 for Django Web app

I'm deploying a Django web app in production on Heroku. I receive a Server Error (500) after checking with heroku logs --tail.

I'm not sure how to get rid of the user warning which may be causing the issue.

Note, I'm running the app from a prod.py file with my wsgi.py set as:

wsgi.py

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings.prod") # mysite.settings.prod when in prod

application = get_wsgi_application()

requirements.txt

dj-database-url==0.5.0
Django==2.1.2
django-heroku==0.3.1
# psycopg2==2.7.5
psycopg2-binary==2.7.5
pytz==2018.6
whitenoise==4.1
gunicorn==19.6.0

EDIT

Log File from Heroku CLI

I've aligned the Heroku PostgresQL version between my local dev and production and added PostgresQL in local dev to be more consistent. The site works when I test DEBUG=True. I can't find any error in the Chrome console log

Current Heroku log is:

I found my solution.

Step 1

Add this to the production settings file (source for this code is from here):

# Logging

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console'],
             'level': os.getenv('DJANGO_LOG_LEVEL', 'DEBUG'),
        },
    },
}

Step 2

Ensure that you run python manage.py collectstatic --noinput locally and use git push heroku master to push your code to the Heroku server. Do this in Heroku CLI too using heroku run python manage.py collectstatic --noinput

Step 3

Use heroku logs --tail to catch any errors which will be highlighted by calling the code in Step 1. In my case I had:

ValueError: Missing staticfiles manifest entry for 'assets/css/main.css'

Moreover, I used the below code to eliminate the warning about psycog binary library.

conn = psycopg2.connect(DATABASE_URL, sslmode='require')

and import psycopg2 in my base settings file.

Lastly, there was some discussion elsewhere about Whitenoise and Static file directories.

I used the following setup:

import os
import dj_database_url
import django_heroku
import psycopg2
# import sys
# from secrets import *

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__))

# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/2.0/howto/deployment/checklist/

# Application definition

INSTALLED_APPS = [
    # Disable Django's own staticfiles handling in favour of WhiteNoise, for
    # greater consistency between gunicorn and `./manage.py runserver`. See:
    # http://whitenoise.evans.io/en/stable/django.html#using-whitenoise-in-development
    'whitenoise.runserver_nostatic',
    'django.contrib.staticfiles',
    'landing',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
]

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

ROOT_URLCONF = 'mysite.urls'

WSGI_APPLICATION = 'mysite.wsgi.application'

AUTH_PASSWORD_VALIDATORS = [
    {
        'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
    },
    {
        'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
    },
]

# Internationalization
# https://docs.djangoproject.com/en/2.0/topics/i18n/

LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'UTC'
USE_I18N = True
USE_L10N = True
USE_TZ = True

ADMINS = (('Webmaster','[email protected]'))
MANAGERS = ADMINS

# Change 'default' database configuration with $DATABASE_URL.
# DATABASES['default'].update(dj_database_url.config(conn_max_age=500, ssl_require=True))

# Honor the 'X-Forwarded-Proto' header for request.is_secure()
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.0/howto/static-files/

STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles')
STATIC_URL = '/static/'

# Extra places for collectstatic to find static files.
# STATICFILES_DIRS = [
#     os.path.join(PROJECT_ROOT, 'static'),
# ]

# Simplified static file serving.
# https://warehouse.python.org/project/whitenoise/
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

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

Lastly, in the wsgi.py file, ensure this config:

import os

from django.core.wsgi import get_wsgi_application
# Whitenoise should not appear here: http://whitenoise.evans.io/en/stable/changelog.html#v4-0

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings.prod") # mysite.settings.prod when in prod

application = get_wsgi_application()
