Bug: ValueError when executing sam init

[ElrohirGT]

Description:

Hi! First time SAM user here! I tried to install SAM using the package from Nix. I tried running the command sam init.

I tried searching for a similar issue but couldn't find one for the sam init command, only for sam deploy.

Steps to reproduce:

Install sam from nix. Here's a basic flake to do so:

{
  description = "A very basic flake";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-23.11";
    systems.url = "github:nix-systems/default";
    devenv = {
      url = "github:cachix/devenv";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  nixConfig = {
    extra-trusted-public-keys = "devenv.cachix.org-1:w1cLUi8dv3hnoSPGAuibQv+f9TZLr6cv/Hm9XgU50cw=";
    extra-substituters = "https://devenv.cachix.org";
  };

  outputs = {
    self,
    nixpkgs,
    systems,
    devenv,
    ...
  } @ inputs: let
    forEachSystem = nixpkgs.lib.genAttrs (import systems);
  in {
    packages = forEachSystem (
      system: let
        # dbPort = "5433";
        pkgs = import nixpkgs {inherit system;};
      in {
        # For setting up devenv
        devenv-up = self.devShells.${system}.default.config.procfileScript;
      }
    );

    devShells = forEachSystem (system: let
      pkgs = import nixpkgs {inherit system;};
    in {
      default = devenv.lib.mkShell {
        inherit pkgs inputs;
        modules = [
          {
            packages = with pkgs; [
              # General
              awscli2
              aws-sam-cli
            ];
          }
        ];
      };
    });
  };
}

Hey @ElrohirGT, thanks for creating the issue. I wasn't able to reproduce the issue, however, it seems like the package manager you are using is giving you an outdated version of SAM CLI. We don't own or distribute through Nix so we have no control over it. I recommend using our native installers as outlined in our documentation. Let us know if this helps!

[ElrohirGT]

You're right! Thanks a bunch it works now that I use the latest version!

The problem for someone else using nix too was that in my flake I was referring to:

inputs = {
    nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-23.11";
...

When I should be referring to:

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

To get the latest version of everything. Thanks for the help @mildaniel and sorry for the inconvenience!
