Getting error in bindfs configuration for Flatpak stuff

Hello anyone. I have some problems with piece of configurations to configure bindfs for Flatpak fonts & icons support. This day I update my Flakes and I get this error in rebuild proccess. This is my screenshot to describe it.

The configs is :

  # bindfs for Flatpak fonts & icons integration.
  system.fsPackages = [ pkgs.bindfs ];
  fileSystems = let
    mkRoSymBind = path: {
      device = path;
      fsType = "fuse.bindfs";
      options = [ "ro" "resolve-symlinks" "x-gvfs-hide" ];
    };
    aggregatedIcons = pkgs.buildEnv {
      name = "system-icons";
      paths = with pkgs; [
        #libsForQt5.breeze-qt5  # for plasma
        gnome-themes-extra
      ];
      pathsToLink = [ "/share/icons" ];
    };
    aggregatedFonts = pkgs.buildEnv {
      name = "system-fonts";
      paths = config.fonts.packages;
      pathsToLink = [ "/share/fonts" ];
    };
  in {
    "/usr/share/icons" = mkRoSymBind "${aggregatedIcons}/share/icons";
    "/usr/local/share/fonts" = mkRoSymBind "${aggregatedFonts}/share/fonts";
  };
}

My question is how to solve it? This configs based on Using bindfs for font support. Thanks for your help, and sorry my English :pray:t3:
