Https to subdomain

Hello, I have a domain (usewarlock.com) that points to a netlify site and I have a subdomain (api-v1.usewarlock.com) that points to a CNAME on Heroku. Shouldn’t Https be propagated to my subdomain?

Nope! We have no intention or ability to provide SSL certificates for sites we do not host. You’ll need to do that on Heroku’s side.
