Hi @jackrous! I'm Dosu and I’m helping the Langchain-Chatchat team.

你的报错（如 "Invalid port: ':1'" 和 "'NoneType' object is not iterable"）主要原因是 no_proxy 环境变量中包含了未加方括号的 IPv6 地址（如 ::1），导致 httpx 解析 host:port 时出错，API 请求失败，最终返回 None，触发后续 TypeError 和 AttributeError。

解决方法：

1. 检查你的环境变量 no_proxy（或 NO_PROXY），如果有 ::1，请改成 [::1]，即：

   export no_proxy=127.0.0.1,localhost,[::1]
   

2. 检查 settings.py 或 .env 配置，确保 API host 没有写成 ::1，IPv6 必须用 [::1] 包裹。
3. 建议移除所有代理相关环境变量（如 http_proxy、https_proxy），确保本地 API 通信不被代理干扰。
4. 升级 httpx 到 0.27.2 及以上版本：

   pip install httpx==0.27.2 -U
   

5. 修改后重启所有相关服务。

参考：相关 issue 说明和代码修正（包含 bracket 处理 IPv6 的代码片段）。

这样配置后，API 请求会恢复正常，知识库对话功能也能正常使用。

[dosubot]

你的报错 “Invalid port: ':1]'” 说明 API 地址的端口配置依然有问题，通常是配置文件或环境变量里端口写成了 :1 或多了括号、冒号。

请按以下方式排查和修正：

1. 检查 .env、basic_settings.yaml、model_settings.yaml 等配置文件，确保 API_SERVER、api_base_url、public_port 等端口项是合法数字（如 7861），不能有多余的冒号或括号。例如：

   API_SERVER:
     host: 127.0.0.1
     port: 7861
     public_host: 127.0.0.1
     public_port: 7861

2. 检查环境变量，确保没有 :1、[::1]、::1 之类的内容出现在端口字段里。端口必须是纯数字。
3. 检查 no_proxy 环境变量，IPv6 必须写成 [::1]，不能写成 ::1 或 [:1]，推荐如下：

   export no_proxy=127.0.0.1,localhost,[::1]
   

4. 移除所有代理相关环境变量（如 http_proxy、https_proxy、all_proxy），避免代理干扰本地 API 通信。
5. 修正后，重启所有 chatchat 相关服务。

如果你已经做了上述操作但问题依旧，请贴出你的 API_SERVER、api_base_url、no_proxy 等相关配置内容，方便进一步定位。

参考：官方 issue 详细说明和修正方法

[dosubot]

你的报错是因为 API 地址中的端口被错误地解析成了 :1]，这通常是由于配置文件或环境变量（尤其是 no_proxy、API_SERVER、api_base_url 等）里端口或 IPv6 地址写法不规范导致的。请按以下顺序排查：

1. 检查 .env、basic_settings.yaml、model_settings.yaml 等配置文件，确保所有端口字段（如 port、public_port）都是纯数字（如 7861），不能有冒号、方括号或其他字符。
2. 检查环境变量，尤其是 no_proxy，IPv6 必须写成 [::1]，不能写成 ::1 或 :1]，正确写法示例：

   export no_proxy=127.0.0.1,localhost,[::1]
   

3. 移除所有代理相关环境变量（如 http_proxy、https_proxy、all_proxy），避免代理干扰本地 API 通信。
4. 修改后重启所有相关服务。

如果你不确定哪里有问题，可以在 Python 里打印下 api_url，确认它的格式应该类似于 http://127.0.0.1:7861 或 http://[::1]:7861，端口必须是数字，不能有多余符号。

详细原理和修正代码见 官方 issue 5410。

如还有问题，建议贴出你的相关配置内容（如 .env、no_proxy 等），方便进一步定位。

[dosubot]

你的 embedding 报错（failed to create Embeddings for model: bge-large-zh-v1.5 和 'NoneType' object has no attribute 'embed_documents'）根本原因是：Langchain-Chatchat 没有正确获取到 bge-large-zh-v1.5 的模型配置信息，导致 get_Embeddings 返回 None。虽然 xinference list 能看到模型，但如果 model_settings.yaml（或 settings.py）里没有把 bge-large-zh-v1.5 正确列在 MODEL_PLATFORMS 的 embed_models 下，系统就找不到它，初始化失败。

请按以下步骤排查和修正：

1. 检查 model_settings.yaml 或 settings.py 配置
   确认 bge-large-zh-v1.5 是否在 xinference 平台的 embed_models 里。例如：

   MODEL_PLATFORMS:
     - platform_name: xinference
       platform_type: xinference
       api_base_url: http://127.0.0.1:9997/v1
       embed_models:
         - bge-large-zh-v1.5

   如果 embed_models 为空或没有 bge-large-zh-v1.5，get_Embeddings 就会失败。配置原理参考

2. 确保 DEFAULT_EMBEDDING_MODEL 一致
   DEFAULT_EMBEDDING_MODEL 必须和 embed_models 里的名字完全一致（区分大小写）。

3. 重启 xinference 和 chatchat 服务
   配置修改后，重启所有相关服务。

4. 如依然报错，建议切换 embedding 模型测试
   bge-large-zh-v1.5 在部分环境下会有兼容性问题，可以尝试用 bge-m3 或 nomic-embed-text，方法见官方 issue。

5. 重新初始化知识库向量库
   配置无误后，运行：

   chatchat kb -r
   

   或

   python chatchat/cli.py kb --recreate-vs
   

   重新生成向量库，避免旧 embedding 兼容性问题。参考

如果还有问题，可以用 curl 或 http 请求直接访问 xinference 的 embedding 接口，确认端口和模型服务可用。

核心：embedding 名称和平台配置必须完全匹配，否则 get_Embeddings 会返回 None，导致你遇到的所有报错。详细原理
