Invalid order function for sorting with long css line

[Rolv-Apneseth]

So apologies if this has been explained elsewhere, or this is not an issue with this plugin as it seems, but I couldn't find any reference to it. I am having a minor issue when editing minimized css files (i.e. the whole file is on a single line). The error given is:

Error executing vim.schedule lua callback: ...ite/pack/packer/start/nvim-navic/lua/nvim-navi
c/init.lua:77: invalid order function for sorting

No error is given and the plugin works as expected on regular css files where all the code is on separate lines. I am using the default setup options if that makes any difference, and am displaying it using:

vim.o.winbar = "%{%v:lua.require'nvim-navic'.get_location()%}"

Now, this is not major because this plugin isn't the most useful for css files anyways so I can just not attach it when the language server is cssls and then of course no error shows up. If there is however a way to fix this, perhaps you could point me in the right direction and I could put in a pr for it?

Forgot to provide an example sorry, here is code that causes this issue for me (random example of a minified css file)

Got the same error in a html file. Here is the full stacktrace:

Hmm.. Seems that sorting function can be improved.. @smjonas Can you share the html code that triggers this issue?

I cannot, unfortunately (I was not able to reduce the HTML in a reasonable amount of time such that it does not contain sensitive data while still triggering the error). Maybe the CSS that @Rolv-Apneseth provided helps?

Hi @SmiteshP, I've also got the same error in a html files. It's a sendmail's libmilter's document which can be downloaded in this website. Download the sendmail-current.tar.gz, untar it and open the libmilter/docs/api.html will get the error.

Here's my error log:

Error executing vim.schedule lua callback: ...ite/pack/packer/start/nvim-navic/lua/nvim-navic/init.lua:77: invalid order function for sorting

And my nvim-navic's config (using packer.nvim):

    use({
      "SmiteshP/nvim-navic",
      requires = "neovim/nvim-lspconfig",
      config = function()
        require("nvim-navic").setup({
          highlight = true,
        })
      end,
    })
