COPR repo not generating AppStream metadata

I can’t figure out why AppStream metadata isn’t being generated for my COPR repo. I have the “Generate AppStream metadata” setting enabled, and the packages with metainfo do install them to the correct location. But when I look at the repo metadata at https://packages.redhat.com/api/pulp-content/public-copr/electricbrass/doom/fedora-44-x86_64/repodata/repomd.xml, it’s missing the appstream info, and the packages don’t show up at all in GNOME Software. Does anyone know what I’m doing wrong here?
