B13\Container\Tca\Registry::isContainerElement(): Argument #1 ($cType) must be of type string,

[sivaprasad1988]

Hello everyone,

After updating to b13/container 3.1.4, I encountered the following error:

B13\Container\Tca\Registry::isContainerElement(): Argument #1 ($cType) must be of type string, null given, called in /var/www/typo3/releases/1.0.81/vendor/b13/container/Classes/Listener/PageContentPreviewRendering.php on line 33 (0).
When I revert to 3.1.3, everything works as expected. Has anyone else faced this issue, or is there a known fix for this?

Thanks in advance!

Best regards,

@achimfritz I used container version 3.1.5, but it seems like I'm still getting the same error as before. After checking, the expected changes don’t appear to be included in 3.1.5. Any idea why that might be?
