Override Question

[suasuasuasuasua]

Hi, I was trying to pull newer changes from the v4.1.0 tag. I tried this overrideAttrs (ref: https://discourse.nixos.org/t/nixpkgs-overlay-for-mpd-discord-rpc-is-no-longer-working/59982/2), but for some reason I'm getting an error at the very end.

        nh.overrideAttrs rec {
          pname = "nh";
          version = "4.1.0";

          src = fetchFromGitHub {
            owner = "nix-community";
            repo = "nh";
            rev = "v${version}";
            hash = "sha256-OiuhBrJe1AyVxC+AV4HMJ+vhDvUfCyLpBmj+Fy7MDtM=";
          };
          cargoDeps = pkgs.rustPlatform.fetchCargoVendor {
            inherit src;
            hash = "sha256-/tbmzGUd1b4oa+29+eFdkE4l8vxMoIdHx40YgErY9pY=";
          };
        }

Am I overriding this package correctly? I guess I don't get it for Rust packages. The answers that I've found online don't work or are outdated.
