[Feature Request]: Update documents' meta_fields api doesn't work

[must-jpg]

Is there an existing issue for the same feature request?

• [x] I have checked the existing issues.

Is your feature request related to a problem?

Does the current python-sdk or api allow for getting the metadata for each document?

Describe the feature you'd like

It will be great if metadata field is also returned when we list the documents in a dataset. I want to create a separate application that is connected to the deployed ragflow and use structured extractor to generate metadata and later update the document meta_field. So it will be great if we can retrieve the existing metadata for each document.
