    'django.contrib.staticfiles',

pip install django.contrib.staticfiles

pip install django-rest-swagger

schema_view = get_swagger_view(title='Your API Documentation')

urlpatterns = [
    # ... other URL patterns ...
    path('swagger/', schema_view),
    # ... other URL patterns ...
]

python manage.py collectstatic

Step 10: If the problem persists, review the Django Rest Swagger documentation for any updates or known issues.
