Logging on version 5.2.6

Hi, folks.

Log::info($message) is not working for me. For example:

use Log;

class MyController extends BaseController
{
    public function index()
    {
        Log::info("called: index()");
    }
}

XDebug throws a fatal error: " Fatal error: Call to a member function error() on a non-object in /var/www/api/vendor/laravel/lumen-framework/src/Exceptions/Handler.php on line 36"
