infrastructure-vector-store-query-query-on-milvusvectorstore-fails-when-node-ids-are-a6a18ea2

THEN Modify the query method in MilvusVectorStore to check if query.filters is not None before attempting to join with FilterCondition. When filters is None, only use node_ids to construct the expression. This prevents a TypeError when query.filters is None.

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)}]")
