THEN Update the query method to handle the case where filters is None. When filters is None or empty, construct the expression using only node_ids if provided. In the MilvusVectorStore.query method, add a guard: if query.filters is None or not query.filters.filters, then only use node_ids to build the filter expression instead of attempting to combine with FilterCondition.

# Inside MilvusVectorStore.query method:
if query.filters is not None and query.filters.filters:
    expr.extend(_to_milvus_filter(query.filters))
else:
    if query.node_ids:
        expr_list = ['"' + entry + '"' for entry in query.node_ids]
        expr.append(f"{MILVUS_ID_FIELD} in [{','.join(expr_list)}]")
