Codeium triggers error about unfree package even with nixpkgs.config.allowUnfree set

[vendion]

In my flake I have nixpkgs.config.allowUnfree set like so

  nixpkgs = {
    overlays = [
      outputs.overlays.default
    ];
    config = {
      allowUnfree = true;
    };
  };

But yet, every time I do a rebuild I have to explicitly set the NIXPKGS_ALLOW_UNFREE environment variable due to codeium. Codeium is being installed as I have plugins.windsurf-nvim.enable explicitly set in my NixVim settings. Is there anywhere else/another way I need to tell Nix I'm okay with unfree packages being installed on my system?

Is this in your NixOS/HM or Nixvim configuration?
By default, Nixvim instanciates its own nixpkgs instance.
See https://nix-community.github.io/nixvim/NeovimOptions/nixpkgs/index.html for more details.

Feel free to come back if this does not fix your issue.

To clarify, you need to use nixvim's nixpkgs.config.allowUnfree option not a different module-set's (home-manager, nixos, etc).

This means you will probably be configuring programs.nixvim.nixpkgs.config.allowUnfree.

Except if you have useGlobalPkgs enabled.
