Don't really know how my flake is wrong#132

Hi, I am trying to install nix-alien to run a pre-made binary for my class. I modified the flake format a bit to function with my current flake. If you could review flake.nix and tell me what I did wrong, that would be great! ``` { inputs = { nixpkgs.follows = "nixos-cosmic/nixpkgs"; # NOTE: change "nixpkgs" to "nixpkgs-stable" to use stable NixOS release chaotic.url = "github:chaotic-cx/nyx/nyxpkgs-unstable"; nixos-cosmic.url = "github:lilyinstarlight/nixos-cosmic"; nix-alien.url = "github:thiagokokada/nix-alien"; }; outputs = { self, nixpkgs, nixos-cosmic, chaotic, nix-alien }: { nixosConfigurations = { # NOTE: change "host" to your system's hostname NixEyes = nixpkgs.lib.nixosSystem { modules = [ { nix.settings = { substituters = [ "https://cosmic.cachix.org/" ]; trusted-public-keys = [ "cosmic.cachix.org-1:Dya9IyXD4xdBehWjrkPv6rtxpmMdRel02smYzA85dPE=" ]; }; } ({ self, system, ... }: { environment.systemPackages = with self.inputs.nix-alien.packages.${system}; [ nix-alien ]; # Optional, needed for `nix-alien-ld` programs.nix-ld.enable = true; }) nixos-cosmic.nixosModules.default chaotic.nixosModules.default ./configuration.nix ]; }; }; }; } ``` [Ill attach my configuration.nix to a paste as well ](https://hastebin.com/share/moticodulu.bash)
