发生错误：ExceptionGroup: unhandled errors in a TaskGroup (1 sub-exception)

[xingxiaoyang]

第一次安装完成后，最简单的对话报错 。
查看后台，服务启动时，log如下：

DEEPSEEK_API_KEY exists: False
QWEN3_VL_8B_API_KEY exists: False
DEEPSEEK_API_URL: None
QWEN3_VL_8B_API_URL: None

但是我在config.toml里是有配置的

developer_mode设置为true后log是否有明显的报错？
然后你是用的bash run.sh启动的还是在两个终端分别启动mcp server和client？
试试在界面上输入url和key是否有相同问题

1. developer_mode=true，没有明显的报错
2. 用bash run.sh 和两个中断分别启动，结果是一样的，只是在启动的时候报key不存在那些。
3. 在界面上输入url和key，结果是一样的。

是mac还是windows还是linux?
python --version以及pip list复制一下看一下版本

+1。我之前安装完成后对话是是这个。在这个步骤卡起了ExceptionGroup: unhandled errors in a TaskGroup (1 sub-exception)

[Anlittledy]

我们刚刚更新了代码，在遇到ExceptionGroup: unhandled errors in a TaskGroup (1 sub-exception)这种错误时会在控制台完整打印报错信息，麻烦git pull更新一下代码，再按照原来的方式运行，然后发一下控制台输出的详细报错信息，谢谢！

你贴的信息里有http_proxy.py，可能是你的代理接管了到127.0.0.1的请求。试一下不走代理

NO_PROXY=127.0.0.1,localhost uvicorn agent_fastapi:app --host 127.0.0.1 --port 7860

httpcore.ConnectError: All connection attempts failed

The above exception was the direct cause of the following exception:

现在是mcp/client/streamable_http.py里面httpx.ConnectError: All connection attempts failed，是 Client 请求MCP Server没通，大概率是MCP Server没成功启动。检查一下 MCP Server 那边是否成功启动，有没有报错。如果成功启动，应该看到类似如下内容：

INFO:     Started server process [84747]
INFO:     Waiting for application startup.
StreamableHTTP session manager started
INFO:     Application startup complete.
INFO:     Uvicorn running on http://127.0.0.1:8001 (Press CTRL+C to quit)
