Cookie-List: Undefined array key "klaro"

[iw-hotze]

Hello we use your extension in TYPO3 version 12 and get the following error in the cookie list output:

PHP Warning: Undefined array key "klaro" in .../typo3conf/ext/we_cookie_consent/Classes/Controller/ConsentController.php line 135

Are there any approaches where the problem could lie?

Furthermore, we have used the extension in a TYPO3 version 10.4. and we have noticed an error where categories with umlauts cause an error. The array "$klaroConfig" contains an error due to an umlaut and cannot be encoded.

Edit: I also get an error in the backend when exporting json under TYPO3 version 12.

PHP Warning: Undefined property: Websedit\WeCookieConsent\Controller\BackendController::$response in /usr/www/users/energy/typo3cms12/typo3conf/ext/we_cookie_consent/Classes/Controller/BackendController.php line 95
