I am running NIXOS with Hyprland and when I updated hyprland/waybar I get this same error. If I revert the workspaces are restored. Please let me know if you need more information but this is preventing people from upgrading other packages like pyprland, browsers, etc Thank you

Since Hyprland changed where its socket is located Waybar had been updated to the new location, but nixpkgs has not yet updated Waybar with the fix.

I fixed it by using Waybar's flake instead and using the package in the flake in the home-manager modules "package" option, e.g.:

programs.waybar =  {
  enable = true;
  package = inputs.waybar.packages.x86_64-linux.waybar;
};

You may have to use a slightly different package setting. I use snowfall-lib, so it might change how one gets to the package.
