Right, but even switching to just luks, the same error occurs, since it’s searching for the type in lib/types/table.nix

I've tried using the following configuration, but it fails since it's missing the partition table type:

{
  disko.devices.disk."nvme0" = {
    type = "disk";
    device = "/dev/disk/by-id/nvme-ID";
    content = {
      luks = {
        size = "100%";
        content = {
          type = "luks2";
          name = "luks-0";
          passwordFile = "/tmp/disko/luks/nvme0.key";
          askPassword = false;
          extraFormatArgs = [
            "--cipher=aes-xts-plain64"
            "--hash=sha512"
            "--key-size=512"
            "--iter-time=5000"
            "--header=/dev/disk/by-id/usb-ID-part2"
          ];
          extraOpenArgs = [
            "--header=/dev/disk/by-id/usb-ID-part2"
          ];
          settings = {
            header = "/dev/disk/by-id/usb-ID-part2";
            preLVM = true;
            allowDiscards = true;
          };
          initrdUnlock = true;
          content = {
            type = "lvm_pv";
            vg = "NixOS";
          };
        };
      };
    };
  };
}

oh you're just missing type entirely. that's what's happening here (the disko test i just made for bare luks worked fine). try this:

{
  disko.devices.disk."nvme0" = {
    type = "disk";
    device = "/dev/disk/by-id/nvme-ID";
    content = {
      type = "luks";
      name = "luks-0";
      passwordFile = "/tmp/disko/luks/nvme0.key";
      askPassword = false;
      extraFormatArgs = [
        "--cipher=aes-xts-plain64"
        "--hash=sha512"
        "--key-size=512"
        "--iter-time=5000"
        "--header=/dev/disk/by-id/usb-ID-part2"
      ];
      extraOpenArgs = [
        "--header=/dev/disk/by-id/usb-ID-part2"
      ];
      settings = {
        header = "/dev/disk/by-id/usb-ID-part2";
        preLVM = true;
        allowDiscards = true;
      };
      initrdUnlock = true;
      content = {
        type = "lvm_pv";
        vg = "NixOS";
      };
    };
  };
}

tcurdt: here is how I do it

Super interesting. Thank you!

I am not quite sure how you are using it though. I see installation-cd-base.
Do you create an ISO from this to start the install?
