I want to get the site information of tk domain in python-whois

I want to get the site information of gg domain in python-whois.However, it is not possible to obtain information about a domain in a particular TLD(e.g. example.tk for the tk domain).

import whoisres = whois.whois("example.tk")print(res)

{"domain_name": null,"registrar": null,"whois_server": null,"referral_url": null,"updated_date": null,"creation_date": null,"expiration_date": null,"name_servers": null,"status": null,"emails": null,"dnssec": null,"name": null,"org": null,"address": null,"city": null,"state": null,"registrant_postal_code": null,"country": null}

I tried specifying a whois.dot.tk server as an argument, but I got an error saying that such a host is unknown.If you know, please help me.
