Nix package not working after rollout

General

I am trying to use ffmpeg. It is working in firebase studio but it does not work after rollout.

{pkgs}: {
  # Which nixpkgs channel to use.
  channel = "stable-24.11"; # or "unstable"
  # Use https://search.nixos.org/packages to find packages
  packages = [
    pkgs.nodejs_20
    pkgs.ffmpeg
  ];

Same issue. I even installed ffmpeg and created paths to it. Still, it does not work nor is an ffmpeg command found on the client side, after production.
