Argument 1 must be of the type string, null given, called in TtNews.php on line 4050

I created a new page [V10.4.20] with bootstrap and now I have installed the tt_news-extension [v10.0]

Now I want to show my news on my page but there is an error:

Argument 1 passed to TYPO3\CMS\Frontend\Resource\FilePathSanitizer::sanitize() must be of the type string, null given, called in /typo3conf/ext/tt_news/Classes/Plugin/TtNews.php on line 4050

Same here. Is there any fix for this issue?
