hello there! I have a problem with flake-utils-plus and I was told to consult with David Arnold. this is what I'm getting on nix flake show:

git+file:///home/mihai/Documents/code/git/nur
├───overlay: Nixpkgs overlay
├───packages
│   ├───aarch64-linux
error: attribute 'filterPackages' missing

       at /nix/store/i4ihaf9zkrrddjqbnhcxpwrwbfpr2qhb-source/lib/fromOverlays.nix:39:12:

           38|           **/
           39|         let
             |            ^
           40|

any idea why this happens?

error: value is a function while a set was expected

       at /nix/store/i4ihaf9zkrrddjqbnhcxpwrwbfpr2qhb-source/lib/fromOverlays.nix:53:29:

           52|             let
           53|               allOverlays = attrValues overlays;
             |                             ^
           54|

So memory refresh resulted in:

• First the contructor needs to consume self.overlays to become a builder
• Then the builder needs to consume channels to build

{
  description = "NUR packages";

  inputs = {
    nixpkgs.url = github:NixOS/nixpkgs;
    utils.url = github:gytis-ivaskevicius/flake-utils-plus/staging;

    nixpkgs-osu.url = "github:NixOS/nixpkgs/73b982e62194a5d85827d87b0851aee06932979f";
    nixpkgs-kak.url = "github:NixOS/nixpkgs/e5920f73965ce9fd69c93b9518281a3e8cb77040";


    kakoune-cr = { url = "github:alexherbo2/kakoune.cr"; flake = false; };
    picom-jonaburg = { url = "github:jonaburg/picom"; flake = false; };
  };

  outputs = { self, nixpkgs, utils, ... }@inputs:
    utils.lib.systemFlake rec {
      inherit self inputs;

      overlay = import ./pkgs { inherit inputs; };
      overlays = utils.lib.exporters.internalOverlays { inherit (self) pkgs inputs; };

      # build all packages defined in ./pkgs/default.nix for their respective systems
      outputsBuilder = channels: {
        packages = utils.lib.exporters.fromOverlays self.overlays channels;
      };
    };
}

this is my flake if it helps
