Search results return a blank screen

Error log:
PHP Fatal error: Uncaught TypeError: SimpleSearch\SimpleSearch::createExtract(): Argument #1 ($text) must be of type string, null given, called in ../public_html/core/cache/includes/elements/modx/revolution/modsnippet/41.include.cache.php on line 88 and defined in ../core/components/simplesearch/src/SimpleSearch.php:340

Possible no NULL check in createExtact.
public function createExtract($text, $length = 200,$search = '',$ellipsis = '...') -

I could 'fix' this by adding if(!isset($text)) { $text = ''; } before the call in the SimpleSearch snippet.

 $extract = $search->createExtract($text, $extractLength, $extract,$extractEllipsis);
