Nix / NixOS

I'm trying to patch qt5ct and qt6ct with their kde patch, which im doing like so:

  home.packages = with pkgs; [
    kdePackages.qt6ct.overrideAttrs (finalAttrs: previousAttrs: {
      patches = [
        fetchpatch {
          url = "https://aur.archlinux.org/cgit/aur.git/plain/qt6ct-shenanigans.patch?h=qt6ct-kde";
          hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
        }
      ];
    })

    libsForQt5.qt5ct.override {
      patches = [
        fetchpatch {
          url = "https://aur.archlinux.org/cgit/aur.git/plain/qt5ct-shenanigans.patch?h=qt5ct-kde";
          hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
        }
      ];
    }
  ];

but that im getting this error
