Nil not updating UI or stuck on loading

[gytis-ivaskevicius]

I've been trying out nil but I have consistently messages being stuck like this:

After enabling debug logging (which should be mentioned in README.md) I noticed that it finishes loading inputs and there is nothing suspicious about the log

Log:

Config: (gets parsed to lspconfig)

  use.lspconfig.nil_ls.setup = callWith {
    cmd = [ (getExe pkgs.nil) ];
    inherit capabilities;
    settings = {
      "['nil']".nix = {

Fixed it by:

  setup.fidget = {
    progress.display.progress_ttl = 3;
  };

Not sure if you'd like to keep this issue, probably missing some signal from lsp side to clear it
