Getting an error when trying to output images

[idr4n]

Hi,

In general, Molten is working great for me either in a quarto document or python file, which is awesome. I have been trying to get images working, though, without luck.

I'm on macOS and using Kitty:

NVIM v0.9.5
Build type: Release
LuaJIT 2.1.1692716794
Lua 5.4.6

I have installed magick as dependency of image.nvim with $ luarocks --local --lua-version=5.1 install magick,

Checkhelth for molten:

molten: require("molten.health").check()

  - ADVICE:

My basic neovim config is this one:

  {
    "benlubas/molten-nvim",
    dependencies = { "3rd/image.nvim" },
    build = ":UpdateRemotePlugins",
    ft = { "markdown", "python", "quarto" },
    config = function()
      vim.g.molten_use_border_highlights = true
      -- add a few new things
      vim.g.molten_image_provider = "image.nvim"

      vim.keymap.set("n", "<localleader>mi", ":MoltenInit<CR>")
      vim.keymap.set("n", "<localleader>me", ":MoltenEvaluateOperator<CR>")
      vim.keymap.set("n", "<localleader>ml", ":MoltenEvaluateLine<CR>")
      vim.keymap.set("n", "<localleader>mr", ":MoltenReevaluateCell<CR>")
      vim.keymap.set("v", "<localleader>mr", ":<C-u>MoltenEvaluateVisual<CR>gv")
      vim.keymap.set("n", "<localleader>mo", ":noautocmd MoltenEnterOutput<CR>")
      vim.keymap.set("n", "<localleader>mh", ":MoltenHideOutput<CR>")
      vim.keymap.set("n", "<localleader>md", ":MoltenDelete<CR>")
    end,
  },
  {
    "3rd/image.nvim",
    opts = {
      backend = "kitty",
      integrations = {},
      max_width = 100,
      max_height = 12,
      max_height_window_percentage = math.huge,
      max_width_window_percentage = math.huge,
      window_overlap_clear_enabled = true,
      window_overlap_clear_ft_ignore = { "cmp_menu", "cmp_docs", "" },
    },
    -- version = "1.1.0", -- or comment out for latest
  },

So, basically when initializing the kernel I don't get any errors and normal cells run as expected. Only when running a cell that ask to plot an image I get this error:

Could this be related to the Lua version installed in my system Lua 5.4.6, while magick was installed based on version 5.1?

Thanks in advance for any help on this issue.

I guess this issue has been mentioned in the image.nvim repo, so closing this discussion.
