The function Doctrine\DBAL\Driver\ResultStatement::fetchColumn() has been deprecated: Use fetchOne() instead.

The expression return $this->count = $qb->execute()->fetchColumn() could return the type false which is incompatible with the type-hinted return integer. Consider adding an additional type-check to rule them out.
