Bug: Creating New Page generating error because the Flux Provider 'Page' was not registered correctly

[Sofatraining]

I have checked that the bug exists in the dev-development branch Yes

I have checked that there are no already open issues or recently closed issues about this bug Yes

Describe the bug Creating New Page generating error. FluidTYPO3\Flux\Service\PageService::getPageTemplateConfiguration(): Argument #1 ($pageUid) must be of type int, null given, called in /www/htdocs/.../typo3conf/ext/flux/Classes/Provider/PageProvider.php on line 87 TYPO3 12.4.6 Probably because the Flux Provider 'Page' was not registered correctly Flux Provider 'Content' was registered correctly

Also you can see there are no entries in page properties under 'Page Layouts':

Entries in ext_localconf.php: \FluidTYPO3\Flux\Core::registerProviderExtensionKey('myextensionkey', 'Content'); \FluidTYPO3\Flux\Core::registerProviderExtensionKey('myextensionkey', 'Page'); 'myextensionkey' was of course replaced with the correct key.

To Reproduce Steps to reproduce the behavior:

1. Go to Page
2. Click on 'Create New' Wizard
3. Click on 'Insert Page'

Same error in TYPO3 11.5.31 with flux 10.0.6. If I set extension setting pageIntegration=0, then the problem disappears.
