Cannot set terminal process group (-1): Inappropriate ioctl for device

[lillo42]

Hey folks,
I'm trying to use expert-ls with Neovim, but I'm getting this erro:

bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell

My environment:
OS: 6.18.33.2-microsoft-standard-WSL
Tmux: 3.7
Nix: 2.32.4 (I'm using with nix develop)
Neovim: v0.12.3

{
  description = "A very basic flake";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
  };

  outputs =
    {
      nixpkgs,
      flake-utils,
      ...
    }:
    flake-utils.lib.eachDefaultSystem (
      system:
      let
        # pkgs = nixpkgs.legacyPackages.${system};
        pkgs = import nixpkgs { inherit system; };
      in
      {
        devShells.default = pkgs.mkShell {
          packages = [
            pkgs.beamMinimal29Packages.elixir_1_20
            pkgs.beamMinimal29Packages.expert
            pkgs.nodejs
            pkgs.tailwindcss_4
            pkgs.python315
            pkgs.postgresql_18
          ];
        };
      }
    );
}

That is a warning that I am yet to find a way to fix, but it should be harmless and the bash call should continue to run normally. It "leaks" into the expert logs because we capture stderr and stdout in the same buffer.

Are you seeing any other error after that? Or any other suspicious log?

As a side note, if you are using the nightly releases you should be able to configure the elixir and erlang paths by setting the elixirExecutablePath and erlangExecutablePath options in your nvim lsp config. This will be released in expert 0.2
