Upgrading Laravel 5.1 to 5.2: Missing argument 1 for Illuminate\Auth\AuthManager::createDriver()

Upgrading Laravel from 5.1 to 5.2 gives me an error after upgrading and running the project.

I have followed Laravel's documentation of upgrading from 5.1 to 5.2 (http://ift.tt/1VIIagB).

Also, I updated my config/app.php to the one found here: http://ift.tt/1XLwgBV

After the upgrade, running my Laravel project gives me an error:

ErrorException in AuthManager.php line 16:
Missing argument 1 for Illuminate\Auth\AuthManager::createDriver()

Has anyone upgraded successfully and resolved this error?
