infinite recursion encountered

[marvin-tr-81]

Hi, I would like to start by thanking for this great project. I am quite new to nixos and am still a linux newbie. I have searched for a solution but unfortunately could not find a solution to my problem. I have set up a humble modular flake configuration.

my flake:

{
  description = "marvin's flake";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";

    nixos-hardware.url = "github:NixOS/nixos-hardware/master";

    nixvim = {
      url = "github:nix-community/nixvim";
      inputs.nixpkgs.follows = "nixpkgs";
    };

    stylix = {
      url = "github:danth/stylix";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { nixpkgs, ... } @ inputs: {
    
    nixosConfigurations.marvin-framework = nixpkgs.lib.nixosSystem {
    specialArgs = { inherit inputs; };
      modules = [
        ./hosts/marvin-framework/configuration.nix
        ./nixosModules
        inputs.nixos-hardware.nixosModules.framework-11th-gen-intel
      ];
    };
  };
}

./nixosModules/default.nix contains all my modules

{ ... }:

{
  imports = [
    ./users.nix
    ./hyprland.nix
    ./guiapps.nix
    ./cliapps.nix
    ./systemapps.nix
    ./home-manager.nix
    ./nixvim/nixvim.nix
    ./stylix.nix
    ./systemConfigurations
  ];
}

and finally my stylix.nix file:

{ pkgs, inputs, ... }:

{
  imports = [
    inputs.stylix.nixosModules.stylix
  ];

  stylix.enable = true;
}

Here when I comment out stylix.enable = true line, I do not get any error. But this configuration as it is gives me many headaches. I have not been able to figure out what causes the following error.

error:
       … while calling the 'seq' builtin

          334|         config = checked (removeAttrs config [ "_module" ]);
             |                  ^
          335|         _module = checked (config._module);

          274|           let

             |              ^
         1029|     };

I am sorry if the solution is actually trivial and thanks in advance for your help.

Instead of passing Stylix as a nixos module, I passed it as a home-manager module, and now it works. I still investigate how to enable Stylix as a nixos module.
