When trying to delete page when logged in as BE non admin user - getting exception

An exception occurred while executing 'SELECT COUNT(`uid`) FROM `be_groups` WHERE (`pid` IN (?)) AND (`be_groups`.`deleted` = 0)

Looks like it fails when check if there are records from disallowed tables in "sysext/core/Classes/DataHandling/DataHandler.php" when building query on line 8032.

$count = $query->count('uid')
                    ->from($table)
                    ->where($query->expr()->in(
                        'pid',
                        $query->createNamedParameter($inList, Connection::PARAM_INT_ARRAY)
                    ))
                    ->execute()
                    ->fetchColumn(0);

$inList is string, but expected parameter is array

$query->createNamedParameter([$inList], Connection::PARAM_INT_ARRAY)
