Langchain-Chatchat [BUG] milvus向量库上传文档报错

milvus可以进行知识库文档，但是向milvus上传新的文档报错信息如下：

INFO: 127.0.0.1:57820 - "POST /knowledge_base/search_docs HTTP/1.1" 500 Internal Server Error ERROR: Exception in ASGI application Traceback (most recent call last): File "/root/anaconda3/envs/env_rag/lib/python3.10/site-packages/fastapi/encoders.py", line 322, in jsonable_encoder data = dict(obj) TypeError: 'numpy.float32' object is not iterable

During handling of the above exception, another exception occurred:

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

嘿 @jiyang2024，又见面啦！希望这次我们能一起搞定这个棘手的问题。👾

根据您提供的错误信息，问题出在尝试将numpy.float32对象转换为可迭代对象时。这可能是因为在处理数据时，某个应该是列表或字典的变量被错误地赋值为了numpy.float32对象。

在knowledge_base_page函数中，x变量应该是一个字典，其中包含了知识库中的文档信息。错误信息显示在尝试访问x["id"]，x["page_content"]和x["metadata"].get("source")时，x变量是一个字符串，这就是为什么会出现TypeError: string indices must be integers的错误。

我在Langchain-Chatchat的问题跟踪中找到了一个类似的问题：自定义知识库上传、删除等报错。这个问题的建议解决方案是更新项目代码和依赖项（特别是langchain/fschat），然后再试一次。

如果更新代码和依赖项后问题仍然存在，那么可能需要进一步检查knowledge_base_page函数中处理x变量的代码，确保在处理数据时不会将x错误地赋值为numpy.float32对象。
