the indent is wrong, but the curly braces are ok

grub.cfg is produced by nixpkgs/nixos/modules/installer/cd-dvd/iso-image.nix

with the ISO from https://nixos.org/download.html ...

wget https://channels.nixos.org/nixos-22.05/latest-nixos-minimal-x86_64-linux.iso

mkdir mnt

sudo mount -o loop nixos-*.iso mnt

If I boot in legy mode, I have no problem. If I boot in uEFI mode, then can't boot. Could this be a compatibility problem

but the latest version seems to fail, and only Legey mode works on the Livecd

LiveCD GRUB EFI boot works for me, as of NixOS 22.11.20230318.08ef7dc (Raccoon) .
