Actual behavior

There is no longer any "add metadata" button in the Files page for a dataset.
As a result, there is no way to manually add custom metadata to dataset/documents

also, the API below does not work (using author : alice example from official doc)

NOTE: This works fine in v0.24.0. The issue started after that in the nightlies...

POST ... /metadata/update

{
    "code": 100,
    "data": null,
    "message": "UnboundLocalError(\"cannot access local variable 'target_doc_ids' where it is not associated with a value\")"
}

Expected behavior

No response

Steps to reproduce

1. Upload a file 
2. Click the metadata column
3. No Add button anymore in the metadata modal box
