Auth::once() trying to establish memcached connection

Hi guys.

I just tried installing a fresh install of Lumen. I'm building an API and I don't need sessions, so when I'm authenticating request I'm trying to use Auth::once() which doesn't utilize session/cookies. But that seems to have changed, something is trying to create a session.

I did a vanilla install, enabled dotenv, facades and eloquent and made this simple route:

$app->get('/', function () use ($app) {
    $result = Auth::once(['email' => 'email@example.com', 'password' => 'myPassword']);
    if ($result) {
      return 'OK';
    } else {
      return 'ERROR';
    }
});

But I'm getting this error:

Whoops, looks like something went wrong.
