Attempting to use ziglang extension fails

[buzmeg]

If I do "nix develop --show-trace", attempting to use ziglang results in an error:

I checked using the method documented and it appears to exist:

nix-repl> t.open-vsx.zig<tab>
t.open-vsx.ziglang  t.open-vsx.zignd

However, it fails with :

My flake.nix is basically a copy of the template as follows:

> cat flake.nix
{
  inputs = {
    nix-vscode-extensions.url = "github:nix-community/nix-vscode-extensions";
    flake-utils.follows = "nix-vscode-extensions/flake-utils";
    nixpkgs.follows = "nix-vscode-extensions/nixpkgs";
  };

  outputs = inputs:
    inputs.flake-utils.lib.eachDefaultSystem
      (system:
        let
          pkgs = inputs.nixpkgs.legacyPackages.${system};
          extensions = inputs.nix-vscode-extensions.extensions.${system};
          inherit (pkgs) vscode-with-extensions vscodium;

          packages.default =
            vscode-with-extensions.override {
              vscode = vscodium;
              vscodeExtensions = [
                extensions.vscode-marketplace.golang.go
                extensions.open-vsx.ziglang  # <-- This line causes a failure
                extensions.open-vsx-release.rust-lang.rust-analyzer
              ];
            };

          devShells.default = pkgs.mkShell {
            buildInputs = [ packages.default ];
            shellHook = ''
              printf "VSCodium with extensions:\n"
              codium --list-extensions
            '';
          };
        in
        {
          inherit packages devShells;
        });
}

Thanks.

@buzmeg ziglang is a publisher. Please, see the Note

[buzmeg]

Indeed they are. :man_facepalming:

Sorry about the noise. I don't know if you could make that error message better or not.

I'll close the issue.
