Application labels aren't unique, duplicates: staticfiles

Question

I'm having trouble figuring out what I'm duplicating here. I'm trying to migrate my files so I can deploy on Heroku. It says that "staticfiles" is duplicated, but I can't see where the conflict is. Does migration need to be done in order to deploy? or is there something wrong with my database?

import dj_database_url
import os

ALLOWED_HOSTS = ['127.0.0.1', '.herokuapp.com']

INSTALLED_APPS = [
    'whitenoise.runserver_nostatic',
    'wiki_app',

    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.postgres',

        },
    },

You need to set a static root which is where Django compiles the static files for serving in production when you run python manage.py collectstatic. The name must be different than the location of your static files in your project.

STATIC_ROOT = str(BASE_DIR.joinpath('staticfiles'))

See the docs for more info.
