It seems like $version can also be of type string; however, parameter $vesion of DBUnt1tled\VO\VObjects\Identity\Uuid::guard() does only seem to accept null, maybe add an additional type check?

Are you sure the doc-type for parameter $vesion is correct as it would always require null to be passed?
