Bug report: On 9.5 the ext. gives some errors

[helmut-winkelbach]

I'm using the extension on multidomain setup (TYPO3 9.5).

Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1294587217: The page is not configured! [type=999][]. This means that there is no TypoScript object of type PAGE with typeNum=999 configured. | TYPO3\CMS\Core\Error\Http\ServiceUnavailableException thrown in file /kunden/.../rp-hosting/.../.../typo3cms/typo3_src-9.5.5/typo3/sysext/frontend/Classes/Controller/TypoScriptFrontendController.php in line 2597. Requested URL: http://....webseiten.cc/?type=999&no_cache=1&tx_comsolitsuggest_suggest[search]=Search%%20&tx_comsolitsuggest_suggest[method]=suggest

I get the following error while typing into search field:
