title: TYPO3 tx_news ErrorHandling for non-existing news
body: <p>When I call a news detail page with a non existing news path segment (www.example.de/news-detail/this-news-does-not-exist/), i get redirected to the 404 page, which is configured in the config.yaml. Is it possible also to control non-existing news urls via the plugin.tx_news.settings.detail.errorHandling configuration (<a href="https://docs.typo3.org/p/georgringer/news/master/en-us/AdministratorManual/Configuration/TypoScript/Index.html?highlight=errorhandling#detail-errorhandling" rel="nofollow noreferrer">https://docs.typo3.org/p/georgringer/news/master/en-us/AdministratorManual/Configuration/TypoScript/Index.html?highlight=errorhandling#detail-errorhandling</a>)? Or is there another way to bypass the 404 handling or to configre the 404 error handling specially for news errors?</p>
