Transparent background not working

[darteyy]

Maybe I am doing something wrong but I cant set up the transparency for my background with this theme. Otherwise I love it!

I am using LazyVim and my config is:

    "ramojus/mellifluous.nvim",
    name = "mellifluous",
    config = function() 
          require("mellifluous").setup({
            transparent_background = {
              enabled = true,
           },
           })

    end,
  },

  {
    "LazyVim/LazyVim",
    opts = {
      colorscheme = "mellifluous",
    },
  },

I get the error as

...ocal/share/nvim/lazy/LazyVim/lua/lazyvim/config/init.lua:216: Vim:E5113: Error while calling lua chunk: ...e/nvim/lazy/mellifluous/lua/mellifluous/utils/shader.lua:17: attempt to call method 'get_hsl' (a nil value)

Nice catch. target is the plain string "NONE" inside this function when transparent background is enabled: https://github.com/ramojus/mellifluous.nvim/blob/1d4884d64b0ebd685f418c29eeb4274f3688eecc/lua/mellifluous/utils/shader.lua#L12
