Is this on the Guix System, or another distro?

Did you check the instructions in the manual section 2.6.1 Locales?

It's likely this error is coming from the guix-daemon, so you'll need to
make sure that GUIX_LOCPATH is set in the environment where the
guix-daemon starts.

On most distros this happens in the systemd unit file with something
like this line in the Service section:

Environment=GUIX_LOCPATH=/var/guix/profiles/per-user/root/guix-profile/lib/locale
