我遇到了同样的问题。

运行的代码如下：

from agentscope.agent import ReActAgent, UserAgent
from agentscope.model import DashScopeChatModel, OpenAIChatModel
from agentscope.formatter import DashScopeChatFormatter, OpenAIChatFormatter, DeepSeekChatFormatter
from agentscope.memory import InMemoryMemory
from agentscope.tool import Toolkit, execute_python_code, execute_shell_command
import os, asyncio

import agentscope

agentscope.init(studio_url="http://localhost:3000")

async def main():
    toolkit = Toolkit()
    toolkit.register_tool_function(execute_python_code)
    toolkit.register_tool_function(execute_shell_command)

    agent = ReActAgent( # react agent来解决问题
        name="Friday",
        sys_prompt="You're a helpful assistant named Friday.",
        model=OpenAIChatModel(
            model_name="deepseek-chat",
            api_key=os.environ["DEEPSEEK_API_KEY"],
            stream=True,
            client_args={
                "base_url": "https://api.deepseek.com/v1",
            },
        ),
        memory=InMemoryMemory(),
        formatter=DeepSeekChatFormatter(),
        toolkit=toolkit,
    )

    user = UserAgent(name="user")

    msg = None
    while True:
        msg = await agent(msg)
        msg = await user(msg)
        if msg.get_text_content() == "exit":
            break

asyncio.run(main())

agentscope的版本：

1.0.8.dev0

报错的流程为：

1. 运行agentscope studio
2. 执行以上代码
3. 在不调用工具时，studio正常输出。如下图：

5. 在studio的输入框输入：帮我写一个shell命令行输出hello world！
6. studio在生成工具调用过程中，后台报错信息如下：

Friday: I'll help you with Python code execution or shell commands. What would you like me to do?
user: 帮我写一个shell命令行输出hello world！
Friday: 我来帮你写一个输出"hello world"的shell命令：Traceback (most recent call last):

8. studio显示看起来正常，实际工具参数是不对的：

[qbc2016]

主要问题发生在当大模型流式返回工具调用的时候，会得到比如 '{"command'这样的字符串，但是，这个字符串经过_json_loads_with_repair函数里的repair_json之后，得到的是一个list ["command"]，所以导致出错。一个解法是在_json_loads_with_repair的这里做一下类型判断，因为当前agentscope里用到这个函数的地方期望得到的都是dict，所以可以先判断json.loads(repaired)的结果，如果不是dict，就返回一个空的dict{}

@qbc2016 感谢！问题解决了！

[ssloth]

@qbc2016 这个会在 框架侧修复吗. 目前还会遇到这个问题.

是的，我们准备让其强制返回字典，可以参考pr #1002
