I tried this out on the same version, and unfortunately I’m not able to reproduce the issue.

Is there more detail available with that error?

Technically `/admin/groups.json` doesn’t exist, in your network tab you should see a `/groups.json` XHR request, which contains the group data… while there’s an `/admin/groups` request for the HTML of the template
