I'm trying to build my first nix package out of the Kana project. My `default.nix' file is below.

When I try to build the application nix tries to fetch https://github.com/ChrisWiegman/kana-cli/archive/v0.10.1.tar.gz which gives a 404. How do I get nix to download the release .tar.gz file to build the application?

{ lib
, buildGoModule
, fetchFromGitHub
, makeWrapper
, go
}:

buildGoModule rec {
  pname = "kana-cli";
  version = "0.10.1";

  src = fetchFromGitHub {
    owner = "ChrisWiegman";
    repo = "kana-cli";
    rev = "v${version}";
    hash = "";
  };

  vendorSha256 = null;

  # This is required for wrapProgram.
  allowGoReference = true;

  nativeBuildInputs = [ makeWrapper ];

  postFixup = ''
    wrapProgram $out/bin/kana-cli --prefix PATH : ${lib.makeBinPath [ go ]}
  '';

  meta = with lib; {
    homepage = "https://github.com/ChrisWiegman/kana-cli";
    description = "WordPress Stuff";
    license = licenses.gpl3;
    maintainers = with maintainers; [ curtismchale ];
  };
}
