Call to undefined method fetch Associative()

[knbknb]

TYPOO3 CMS v10.4.17 here. - The composer based installation from TER with composer require colorcube/content-overview did work for me, but after opening the Web/Info/Content Overview Page I got a PHP error page:

Call to undefined method Doctrine\DBAL\Driver\Mysqli\Mysqli Statement::fetch Associative()

So in ext/content_overview/Classes/Controller/ContentOverviewController.php
I had to replace fetchAssociative() with fetchAll()

I'll post the whole method here . See last line.

    /**
     * Get an alternative language record for a specific page / language
     *
     * @param int $pageId Page ID to look up for.
     * @param int $langId Language UID to select for.
     * @return array pages_languages_overlay record
     */
    public function getLangStatus($pageId, $langId)
    {
        $queryBuilder = GeneralUtility::makeInstance(ConnectionPool::class)->getQueryBuilderForTable('pages');
        $queryBuilder->getRestrictions()->removeAll()->add(GeneralUtility::makeInstance(DeletedRestriction::class));
        return $queryBuilder->select('*')
            ->from('pages')
            ->where(
                $queryBuilder->expr()->eq(
                    'l10n_parent',
                    $queryBuilder->createNamedParameter($pageId, \PDO::PARAM_INT)
                ),
                $queryBuilder->expr()->eq(
                    $GLOBALS['TCA']['pages']['ctrl']['languageField'],
                    $queryBuilder->createNamedParameter($langId, \PDO::PARAM_INT)
                )
            )
            ->execute()
            ->fetchAll();
            //->fetchAssociative();
    }

That is a one-line fix, and it seems to work just fine.
