¿Cómo depurar una consulta en extbase?

En la versión 8.7 LTS , hay que tomar otro camino:

$queryParser = $this->objectManager->get(\TYPO3\CMS\Extbase\Persistence\Generic\Storage\Typo3DbQueryParser::class);
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->convertQueryToDoctrineQueryBuilder($query)->getSQL());
\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($queryParser->convertQueryToDoctrineQueryBuilder($query)->getParameters());
