When updating to v2.4.7 I get following error:
Fatal error: Uncaught Symfony\Component\Debug\Exception\FatalThrowableError: syntax error, unexpected ')' in /var/www/html/vendor/pimcore/customer-management-framework-bundle/src/Newsletter/ProviderHandler/Mailchimp/CustomerExporter/SingleExporter.php:169
When removing the comma at the end of line 168 the error no longer occurs.
Btw, this prevents us from updating to Pimcore 6.5.0 as well, since there's a constraint in the composer.json file.
