Nice!

Yes, people reported that issue just recently:

  https://issues.guix.gnu.org/45174

Until that is fixed, and until the fix propagates to user installations,
I think you’ll have to arrange so that the mirror transparently proxies
requests instead of returning 302, or just returns 404.  How does that
sound?

Thanks,
