How to update porkbun root domain?

[ToNIX-]

I'm trying to update my domain ("domain.top") with an empty host, since I want to update the root domain. I'm leaving the variable host to an empty string ("").https://github.com/qdm12/ddns-updater/discussions

However, I keep getting errors since the host is empty...

"provider": "porkbun",
  	"domain": "domain.top",
  	"host": "",
  	"api_key": "pk1_",
  	"secret_api_key": "",
  	"ip_version": "ipv4"

I've been fiddling with this for way too long, do you guys have any ideas on how to make this work?
