Hello!

I've started my first railway project: a Django + Postgres website. I'm trying to run python manage.py createsupersuer through the railway cli to create my admin user but I'm getting this error:

django.db.utils.OperationalError: failed to resolve host 'postgres.railway.internal': [Errno -2] Name or service not known

The commands I've run are

railway login
railway link
railway service
railway run python manage.py createsuperuser

The database configuration in my django settings is done through dj_database_url

DATABASES = {
    'default': dj_database_url.config(conn_max_age=600, conn_health_checks=True)
}

Am I missing something? What am I doing wrong?
