attempt: on a BIOS boot only system, I am trying to assign a id or uudi to a disko config because /dev/sdx gets switched around and becomes less viable in a raid setup
problem: switching to or using /dev/disk/by-id/<some-device> causes a GRUB2 error after rebuild: "This GPT partition label contains no BIOS Boot Partition; embedding won't be possible."
extra context: this is on a system that already has a disko config setup and im trying to switch it, i cannot bootstrap with /dev/disk/by-id disk either.

I've been stuck on this for a few days, just a nudge in the right direction even if its pointing out something in the docs, or a workaround would be very helpful.

config:
""
{
device ? throw "Set this to your disk device, e.g. /dev/sda",
...
}: {
disko.devices = {
disk.main = {
inherit device;
type = "disk";
content = {
type = "gpt";
partitions = {
boot = {
name = "boot";
size = "1M";
type = "EF02"; # for grub MBR
};
esp = {
name = "ESP";
size = "500M";
type = "EF00";
content = {
type = "filesystem";
format = "vfat";
mountpoint = "/boot";
};
};
swap = {
size = "4G";
content = {
type = "swap";
resumeDevice = true;
};
};
root = {
name = "root";
size = "100%";
content = {
type = "lvm_pv";
vg = "root_vg";
};
};
};
};
};
lvm_vg = {
root_vg = {
type = "lvm_vg";
lvs = {
root = {
size = "100%FREE";
content = {
type = "btrfs";
extraArgs = ["-f"];

          subvolumes = {
            "/root" = {
              mountpoint = "/";
            };

            "/persist" = {
              mountOptions = ["subvol=persist" "noatime"];
              mountpoint = "/persist";
            };

            "/nix" = {
              mountOptions = ["subvol=nix" "noatime"];
              mountpoint = "/nix";
            };
          };
        };
      };
    };
  };
};

};

if /dev/disk/by-id/xxx is just a link to /dev/sdx then im not sure what would grub to fail

during formating or booting?

At first i think miscalculated the sizes. sgdisk would say cannot make partition and refuse going further. That is ok.
But then this, and also partprobe broke and said to reboot, and also sgdisk were spitting random numbers instead of ones that i give to it
