SSL provisioning error: certificate parameter is required

Netlify site:
wondrous-choux-030e1c.netlify.app

Custom domain:
tm85.world

DNS provider:
Porkbun / external DNS

Netlify shows that DNS verification was successful.

When I click “Provision certificate,” Let’s Encrypt provisioning fails with:

“certificate parameter is required when updating an existing certificate”

I also tried Ask Netlify. It indicated that this may be a stale or partial certificate state that requires Netlify Support to reset it on the backend.

Please reset or clear the stale certificate state and reprovision the Let’s Encrypt certificate.
