Example Code

in inject_thread_id_node function  config param can not be passed?
def inject_thread_id_node(state:SearchState,config:dict):
    thread_id = (
        config
        .get("configurable", {})
        .get("thread_id", "default_thread")  # 默认值防错
    )
    return {"thread_id": thread_id}  # ← 仅更新 thread_id
