string ‘en_US.UTF-8’ doesn't represent an absolute path

When I try to deploy my verry first application with the following steps:

cabal2nix . > default.nix with a deployment configuration:

config.nix

let
  region = "eu-east-1";
  accessKeyId = "xxxx";

  ec2 =
    { resources, ... }:
    { deployment.targetEnv = "ec2";
      deployment.ec2.accessKeyId = accessKeyId;
      deployment.ec2.region = region;
      deployment.ec2.instanceType = "m1.small";
      deployment.ec2.keyPair = resources.ec2KeyPairs.my-key-pair;
    };

in
{
  backend = ec2;

  resources.ec2KeyPairs.my-key-pair =
    { inherit region accessKeyId; };
}

as well as release.nix :

{ nixpkgs ? import <nixpkgs> {} }:

nixpkgs.pkgs.haskell.packages.ghc802.callPackage ./default.nix {}

Creating:
nixops create config.nix release.nix -d test
and deploying:
nixops deploy -d test --debug --show-trace

I receive the following error / stacktrace:
