• output.tool 이라는 속성이 없어서 print 해보니 AgentAction List 형태로 출력이 되었습니다.

intermediate_steps = []
final_result = dict()
while True:
    query.update({"intermediate_steps": intermediate_steps})
    output: Union[AgentFinish, AgentAction] = agent.invoke(query)

    if isinstance(output, AgentFinish):
        final_result = output.return_values
        final_result = final_result.get("output")
        break
    else:
        if isinstance(output, list):
            output = output[0]
        print("TOOL NAME : ", output.tool)
        print("TOOL INPUT : ", output.tool_input)
        _tool = tools.get(output.tool)
        observation = _tool.run(output.tool_input)
        intermediate_steps.append((output, observation))


TOOL NAME :  get_word_length
TOOL INPUT :  {'word': 'eudca'}
