"Resource Not Found" when trying to get a specific domain.

I am testing out the API and have run into an error when I try to get a specific domain. I am following the steps on this page: https://docs.ns-api.com/reference/getdomain

I am successfully able to make a call to https://ns-api.com/ns-api/v2/domains and list all domains, but when I add my domain to the URL, I get "Resource not found." My URL looks like this: https://ns-api.com/ns-api/v2/domains/{my_domain}. My domain parameter that I'm providing is literally my domain name formatted as "[name]

[reseller]

.com" (without the quotes).
