[RSS Feed/News] Using session data?

[XenForo]

From my controller, I'm trying to save a session key but that's throwing an error:

Instances of XF\Db\AbstractAdapter cannot be serialized or unserialized in src\XF\Db\AbstractAdapter.php on line 680

My code:
PHP:

$session = $this->session();
$session->set('foo', 'bar');

If I comment out the $session->set() statement, then the error is gone. What am I missing here?
