您的功能请求是否与问题相关？请描述。

我想为Python工具返回一个类作为输出，但是它显示错误：JSON转储失败。例如，对于以下代码，它将返回错误：

@dataclass
class ThoughtStep:
title: str
description: Optional[Any]
props: Optional[dict[str, Any]] = None

The inputs section will change based on the arguments of the tool function, after you save the code

Adding type to arguments and return value will help the system show the types properly

Please update the function name/signature per need

@tool
def my_python_tool(zone_instruction: str, modify_query:str, answer_question:str) -> list:
thought_steps = [
ThoughtStep(title="Look up Zone Instruction", description=zone_instruction, props=None),
ThoughtStep(title="Modify the query with history and zone instruction", description=modify_query, props=None),
ThoughtStep(title="Search relevant documentation", description=None, props=None),
ThoughtStep(title="Answer the questions", description=answer_question, props=None)
]
return thought_steps

描述您希望的解决方案

允许选项注入如何序列化复杂对象

描述您考虑过的替代方案

我目前的解决方法是在Python工具中手动使用jsonoutput = json.dumps(thought_steps, default=lambda o: o.**dict**),并返回一个字符串。

附加上下文

如果需要，我很乐意进一步详细解释。
