Issue when trying to build AsyncAPI CLI using nix

I am trying to build Async API CLI using nix but I keep running into this error

       > > rimraf lib && tsc && oclif manifest && echo "Build Completed"

This is the nix expression that I am using to build it

{ 
  lib
, stdenv
, fetchFromGitHub
, buildNpmPackage
, makeWrapper
, git
, chromium
, ...
}:

buildNpmPackage rec {
  pname = "cli";
  version = "2.14.0";

  src = fetchFromGitHub {
    owner = "asyncapi";
    repo = "cli";
    rev = "v${version}";
    hash = "sha256-HECJelflnfAJ0rTHsu+X5QgazxZdG8Ck2Jyv5ec2Q00=";
  };

  npmDepsHash = "sha256-VVemfHMsM1asxLM+s1MFEzCtinzrj0bVsRKDQaBcjT0=";

  npmBuildScript = "build";
  patches =  [./remove_example.diff ./dir_fix.diff];
  nativeBuildInputs = [ git chromium ];
  ...
}

In one of the patches I modified the build command to stop fetching a zip file and in the other I tried to use the NIX_BUILD_TOP environment variable to get an absolute path to the examples.json file but that also resulted in the same error
