It seems like $stack defined by $this->collector->getCurrentStack() on line 73 can also be of type boolean; however, Http\HttplugBundle\Collector\ProfileClient::collectExceptionInformations() does only seem to accept null|object<Http\HttplugBundle\Collector\Stack>, maybe add an additional type check?
