嗨，@ocpinfo！很高兴再次见到你。希望你一切都好！
感谢您的反馈。根据您提供的错误日志，这个问题似乎是在流处理过程中出现的，而不是由于问题的复杂性导致的。在Langchain-Chatchat应用中，如果在流处理过程中出现错误，就会抛出 "APIError: Caught exception: An error occurred during streaming" 错误。这可能是由于网络问题、服务器问题，甚至是客户端问题。
如果应用程序找不到复杂问题的合适信息，它不会抛出错误。相反，它会使用 "empty" 模板作为提示，如下面的代码所示：
if len(docs) == 0: ## 如果没有找到相关的文档，使用空模板
prompt_template = get_prompt_template("knowledge_base_chat", "empty")所以，您看到的错误不是由于问题的复杂性，而是由于流处理过程中的问题。
关于您提到的类似问题，我在Langchain-Chatchat的问题库中找到了两个相关的已解决问题。这两个问题的讨论和解决方案可能对您有所帮助：
- 调用自己的私有化模型API，能正常返回结果，但是结束之后总会出现API Error的错误
- [BUG] 服务运行成功，对话出错，无返回 | WARNING: Retrying langchain.chat_models.openai.acompletion_with_retry.
._completion_with_retry in 4.0 seconds as it raised APIConnectionError: Error communicating with OpenAI.
关于Langchain-Chatchat v0.2.10的更改，我没有找到可能导致 "APIError: Caught exception: An error occurred during streaming" 错误的相关信息。如果您在更新到v0.2.10之后才开始遇到这个问题，可能需要进一步检查v0.2.10中的更改，看看是否有可能影响到流处理过程。
如果您需要进一步的帮助，或者有更多的信息可以提供，欢迎随时告诉我。
