In the server side an error log like this:

Additional context
Add any other context about the problem here.

in the source file documents_router.py:

documents_router.py:
            workflow_input = {
                "file_data": file_data,
                "document_id": str(document_id),
                "collection_ids": (
                    [str(cid) for cid in collection_ids]
                    if collection_ids
                    else None
                ),

and in the file documents.py:

        ids = [id] if isinstance(id, UUID) else id

maybe should be

        ids = id if isinstance(id, list) else [id]
