Terraform on nixos "permission denied"

I am running NixOS 24.05.20240903.6f6c45b.

Trying to get a devshell setup for working with terraform. This is the basic flake:

# flake.nix
{
  description = "";
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.05";
    futils.url = "github:numtide/flake-utils";
  };
  outputs =
    { self, nixpkgs, futils }: (
      futils.lib.eachDefaultSystem (
        system:
        let
          pkgs = import nixpkgs { inherit system; config.allowUnfree = true; };
        in
        {
          devShell = pkgs.mkShell {
            buildInputs = with pkgs; [
              terraform
              google-cloud-sdk
            ];
          };
        }
      )
    );
}
# provider.tf
terraform {
  required_providers {
    random = {
      source  = "hashicorp/random"
      version = "3.6.2"
    }
    google = {
      source  = "hashicorp/google"
      version = "6.2.0"
    }
  }
}

After doing a nix develop .#, I run terraform init and terraform plan and these are my outputs:

$ terraform init

Initializing the backend...

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

$ terraform plan

what am I doing wrong here, can’t doesn’t the plugin load? Looking at the files in the terraform provider folders permissions look correct

$ ls -lan .terraform/providers/registry.terraform.io/hashicorp/*

though I can’t seem to run the binaries manually

I figured it out… the partition I was working was mounted with ‘noexec’… Once resolved this started working as expected.
