Issues with TYPO3 11.5.8

[machwert]

Settings: TS Constants plugin.tx_wsslider.settings.defaultRenderer = slick

I have included the following TS templates

• WS Slider General Settings
• WS Slider Slick Slider Assets
• WS Slider Slick Slider Settings

Error 1: TYPO3 Version 11.5.8 PHP Version 8.0.17 ws_slider 0.9.8 from TER

In TYPO3 backend, when I try to edit the slider content element, I get the following error message:

str_replace(): Argument #3 ($subject) must be of type array|string, TYPO3\CMS\Backend\Form\Behavior\UpdateValueOnFieldChange given`

Error 2: TYPO3 Version 11.5.8 PHP Version 8.0.8 ws_slider 0.9.8 from Github from 04/25/2022

Here the error is not thrown immediately when trying to edit the slider content item, but only when I try to save it:

TypeError
TYPO3\CMS\Core\DataHandling\DataHandler::setNullValues(): Argument #2 ($haystack) must be of type array, null given, called in /Applications/MAMP/htdocs/typo3_src/typo3_src-11.5.8/typo3/sysext/core/Classes/DataHandling/DataHandler.php on line 9527

Error 3: TYPO3 Version 11.5.8 PHP Version 8.0.8 ws_slider 0.9.8 from Github from 04/25/2022

When I try to create a new slider content item I get the following error message:

(1/1) #1476107295 TYPO3\CMS\Core\Error\Exception
PHP Warning: Undefined array key "dragNdrop" in /Applications/MAMP/htdocs/typo3_src/typo3_src-11.5.8/typo3/sysext/backend/Classes/Form/Container/FlexFormTabsContainer.php line 64

Did you include the according items in PageTS?

Thanks @DavidBruchmann for you reply.

Yes, I have included those PageTS items, but I still get the error with PHP 8.0.8. With PHP 7.4.21 there is no problem.
