TYPO3 frontend error: Form configuration missing

Frontend and Backend Development

Using TYPO3 v12, my custom package YAML setup causes a frontend error with form ‘contactform’. Example config:

CMSconfig:
  Forms:
    storage:
      extensionPaths:
        101: 'EXT:custom_package/Resources/Private/FormLayouts/'
      allowSave: false
      allowRemove: false

Please verify allowed extension paths.

hey, i had a similiar issue once too. check your yaml indentng carefully and make sure there arent any mispelled keys. minor format mistakes can cause these errrors, even if the paths appear right. clearing caches after editing usually helps me out.

The frontend error often indicates that the YAML configuration does not conform to the expected structure in TYPO3 v12. I encountered a similar issue when my extension paths overlooked some new strict requirements in the updated version. Reviewing the YAML file side by side with the official documentation helped identify subtle changes and deprecated keys. In my experience, ensuring that all provided paths are valid and revisiting the configuration schema for potential modifications is crucial. Clearing caches and ensuring that file permissions and paths are correctly set resolved my issue. Testing with a simplified configuration helped isolate the problem effectively.

hey dancingbutterfly, i was wonderin if the new v12 requirs a tweak in the yaml keys? check if the config schema has any depricated fields. how did u eventually sort it out? any extra hints could be fun to explore further
