Tested in the most current version of NixOS.

It is introduced in 2.2.0, check your version?

[novo-max]

I tested it both with version 2.1.2 and 2.2.0 - same behavior for both. My current version is

nixd --version
nixd, version: 2.2.0

Could you please paste the nix snippet shown in your screenshot here?

I changed it since but you can use this one:

{
  inputs = {
    openwrt-imagebuilder.url = "github:astro/nix-openwrt-imagebuilder";
  };
  outputs = { self, nixpkgs, openwrt-imagebuilder }: {
    packages.x86_64-linux.my-router =
      let
        pkgs = nixpkgs.legacyPackages.x86_64-linux;

        profiles = openwrt-imagebuilder.lib.profiles { inherit pkgs; };

        config = profiles.identifyProfile "avm_fritz7412" // {
          # add package to include in the image, ie. packages that you don't
          # want to install manually later
          packages = [ "tcpdump" ];

          disabledServices = [ "dnsmasq" ];

          # include files in the images.
          # to set UCI configuration, create a uci-defauts scripts as per
          # official OpenWRT ImageBuilder recommendation.
          files = pkgs.runCommand "image-files" {} ''
            mkdir -p $out/etc/uci-defaults
            cat > $out/etc/uci-defaults/99-custom <<EOF
            uci -q batch << EOI
            set system.@system[0].hostname='testap'
            commit
            EOI
            EOF
          '';
        };

      in
        openwrt-imagebuilder.lib.build config;
  };
}

Cannot reproduce. It works pretty well as expected on my machine.

How about changing the nix.serverPath to absolute path pointing to nixd 2.2.0 ? I think there may be some launching issue about the version you used. If the issue still occurs, please export NIXD_FLAGS=-log=verbose, lauch vscode again, and paste the logs here.

I can't figure out where the logs are stored. I looked into HOME and /var/log and I can't find it. To clarify I export export NIXD_FLAGS=-log=verbose and then I type codium within the same shell to start VSCode.

It is in your codium. Same window as the terminal and check 'OUTPUT', the logs are written there in "Nix" extension.

Thank you very much @inclyc . I have to apologize for wasting your time since for a couple of days everything is working just fine and all sema-def-not-used do get suppressed when I use the configuration above. Since I created this post I upgraded my NixOS several times so I possibly had outdated "something". All works now! Thank you.
