• This is a bug, not a usage question.
• I added a clear and descriptive title that summarizes this issue.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).
• This is not related to the langchain-community package.
• I read what a minimal reproducible example is (https://stackoverflow.com/help/minimal-reproducible-example).
• I posted a self-contained, minimal, reproducible example. A maintainer can copy it and run it AS IS.

Example Code

config: RunnableConfig = {"configurable": {"thread_id": "1"}}

state = agent.invoke({"messages": [{"role": "user", "content": "福州天气怎么样？5加5等于多少？"}]},config)
while "interrupt" in state:
interrupts = state["interrupt"]
decisions = []
for interrupt in interrupts:
actions = interrupt.value["action_requests"]

    for action in actions:
        print(f"需要人工确认的操作: {action['name']} 参数: {action['args']}")
        decision = input("是否继续？(approve/edit/reject): ")

        if decision == "approve":
            decisions.append({"type": "approve"})

        elif decision == "edit":
            new_query = input("输入修改后的参数: ")
            decisions.append({
                "type": "edit",
                "edited_action": {
                    "name": action["name"],
                    "args": {"query": new_query}
                }
            })
        elif decision == "reject":
            decisions.append({"type": "reject"})

# 所有 action 决策后恢复执行
state = agent.invoke(
    Command(resume={"decisions": decisions}),
    config=config
 )

state["messages"][-1].pretty_print()
