Going of the conversation in the comments, the issue is that you don't have a session.php inside your config directory. The reason this is an issue is because Laravel will use that config file to get the name of the session driver and, like all config values, if it isn't present it will just return null.

Adding the default session config file to that directory should solve your issue.
