Lumen 5.3 environment file

Hello, I having problems with environment file with Lumen. Lumen always is loading .env file without APP_ENV value.

I need to edit app/boostrap/app.php manually :

(new Dotenv\Dotenv(__DIR__.'/../'))->load();


(new Dotenv\Dotenv(__DIR__.'/../'),$envDetected)->load();

Someone else with same problem??
