Frontend Issue: TYPO3 YAML Form Config Not Loading

Frontend and Backend Development
1

TYPO3 v12: My YAML form setup works in the backend editor but fails on the frontend. Verify allowed paths in your configuration. For example:

FormConfig:
  storageOptions:
    permitDir: 'EXT:custom_pkg/assets/forms'

hey, i had this happening too. check if the allowed path exactly matchs the actual file structure and that your config deffination is right. often a tiny typo causes the problem on the frontend.

Based on my experience, the issue might stem from subtle file path mismatches or insufficient permissions rather than a problem with TYPO3 itself. I encountered a similar challenge where cleaning caches and verifying that the file system paths correctly resolved against the production environment fixed the issue. The YAML configuration sometimes overlooked relative paths on the frontend, so I made sure that the directory was defined in a way that the system could consistently locate it. Debugging the error logs further confirmed that the configuration paths needed an update.
