Error when attempting to add domain alias based on customer request

We’re trying to add as an alias to our project upon request of our user. This is a flow we’ve followed numerous times in the past but for some reason we’re getting “domain_aliases is owned by another account”. Our user says they don’t have a Netlify account, so why are we getting this error?
