A lightweight Symfony bundle that automatically transforms validation errors from `#\[MapRequestPayload\]`, `#\[MapQueryString\]`, and `#\[MapUploadedFile\]` attributes into clean, developer-friendly JSON responses. Stop writing repetitive error handling code in every controller. Let this bundle handle it for you.
