Describe the bug

When trying to highlight items that don't have a TS parser, it throws the following error:

What is the severity of this bug?

tolerable (can work around it)

Steps To Reproduce

1. Perform a search that would span files that don't have an installed TS parser
2. Error pops up

Expected Behavior

I think it's reasonable to just not do syntax highlight for files that don't have TS enabled

Minimal example file

No response

Minimal init.lua

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "--single-branch",
    "https://github.com/folke/lazy.nvim.git",
    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  {
    "stevearc/quicker.nvim",
    config = function()
      require("quicker").setup({
        -- add your config here
      })
    end,
  },
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

Beautiful plugin, btw. I was hoping for something like this!

Fixed, thanks for the report!
