So, in the backend/venv/lib/python3.9/site-packages/cities_light/management/commands/cities_light.py after 308 line i put the code

            if not items[ICountry.geonameid]:
                print(ICountry.geonameid)
                print(items)

it returns

Could you help with that? Do you have any ideas?
