TYPO3 Core

Run Upgrade Wizards fails while "Loading upgrade wizards"

System¶

TYPO3: 10.4.11 (composer-based)

Steps to reproduce¶

Have a content element with a pi_flexform containing no data:

INSERT INTO `tt_content` (`CType`, `pi_flexform`) VALUES('form_formframework', '<?xml version=\"1.0\" encoding=\"utf-8\" standalone=\"yes\" ?>\n<T3FlexForms>\n</T3FlexForms>');

Then open install tool and in module "Upgrade" click on "Run upgrade wizard".
