TYPO3\CMS\Backend\Controller\ContentElement\NewContentElementController::getPageInfo(): Return value must be of type array, null returned

[flack]

I just tried updating from frontend_editing 3.3.4 to 4.x (on typo3 11.5), and now all pages I try to open in the backend editor throw this exception.

The end of the backtrace looks like this:

in typo3/sysext/backend/Classes/Controller/ContentElement/NewContentElementController.php line 523
in typo3conf/ext/gridelements/Classes/Hooks/WizardItems.php line 71
in typo3conf/ext/frontend_editing/Classes/Controller/FrontendEditingModuleController.php line 940
in typo3conf/ext/frontend_editing/Classes/Controller/FrontendEditingModuleController.php line 855
in typo3conf/ext/frontend_editing/Classes/Controller/FrontendEditingModuleController.php line 553
in typo3/sysext/backend/Classes/Http/RouteDispatcher.php line 91
(...)

If I go back to 3.3.4 things work normally again. Is this some incompatibility between frontend_editing and gridelements?

@flack Yes there is some issue between the 2 extensions. We are open for all contributions!
