### Enhancements
### Features
### Fixes
- Fix type error when `result_file_type` is expected to be a `FileType` but is `None`
- Fix chunking for elements with None text that has AttributeError 'NoneType' object has no attribute 'strip'.
- Invalid elements IDs are not visible in VLM output. Parent-child hierarchy is now retrieved based on unstructured element ID, instead of id injected into HTML code of element.
