While reading through Meta, I saw this:

Notice that the [Hetzner VPS topic](https://meta.discourse.org/t/hetzner-launches-a-vps-service/78759) is shown to be a link to `undefined`.

The topic itself looks fine:

My suspicion is that the domain is missing in the suggested topics payload, triggering the JavaScript payload to return `undefined`.
