This error can be fixed if you cast the $className to string here: https://github.com/psalm/psalm-plugin-symfony/blob/44f9a695cd7223844ffaa88a2d23b3f7ce658db0/src/Handler/DoctrineRepositoryHandler.php#L48 Or solve why $className is null in the first place..

My system: PHP 8.1.1 psalm/plugin-symfony 3.1.3 vimeo/psalm 4.21.0 doctrine/doctrine-bundle 2.5.6 doctrine/orm 2.11.1 symfony 6.0.4
