[Bug]: controller.py (98) - [ERROR] : local variable 'chunk' referenced before assignment
运行环境
docker
异常情况
我使用的消息平台是napcat（它们都运行在docker中，已经按照wiki调整两者的容器网络），消息平台和LangBot之间的通讯没有问题。 api平台使用的是dify（模型名称设置在这个地方应当不会生效） dify的地址是局域网中的另一台主机。 dify的API Endpoint：http://172.16.0.121/v1 请求运行器是：dify-service-api 当我认为万事大吉想要发送一条测试消息的时候，Langbot的日志中输出了如下内容：
[04-30 12:01:08.698] process.py (42) - [INFO] : 处理 person_1048893645 的请求(0): 1 [04-30 12:01:39.320] chat.py (94) - [ERROR] : 对话(0)请求失败: UnboundLocalError local variable 'chunk' referenced before assignment [04-30 12:01:39.651] controller.py (98) - [ERROR] : local variable 'chunk' referenced before assignment[04-30 12:02:02.198] process.py (42) - [INFO] : 处理 person_1048893645 的请求(1): 2 [04-30 12:02:33.098] chat.py (94) - [ERROR] : 对话(1)请求失败: UnboundLocalError local variable 'chunk' referenced before assignment [04-30 12:02:33.376] controller.py (98) - [ERROR] : local variable 'chunk' referenced before assignment
复现步骤
1、使用docker部署LangBot和NapCat并设置容器网络。 2、启用LangBot消息适配器（aiocqhttp，host:0.0.0.0,port:2280,设置access token） 3、登录NapCat并设置ws客户端，填写ws:// 4、发送测试消息，验证Napcat和LangBot之间是否通讯正常，langbot是否可以接收NapCat消息 5、配置Langbot的provider，使用Dify Service Chat 6、请求运行器使用：dify-service-api 7、再次发送测试消息，验证模型请求功能

把你的 provider.json 文件内容也贴上来看看

最后的runner这里无论是local-agent对接普通的中转api还是使用dify-service-api对接dify都不行
这个问题我这边没法复现，但从代码角度来看，你这里是 langbot 与 dify 的连接可能不正常，导致没有收到任何回复。现在我已经在 #1376 加了个针对这个问题的报错信息，你可以等新版发布之后再试试。
