The issue where the knowledge base answer source displays as "None" and the "Internal Server Error" you're encountering could be due to several factors within the Langchain-ChatGLM application. Here's a focused approach to troubleshoot and potentially resolve these issues:

1. Check Document Queries: Ensure that the queries you're using can successfully match documents within your knowledge base. If no documents are found, the system might default to showing "None" as the source.

2. Verify Document Metadata: The "source" key in your document's metadata is crucial. If this key is missing or the value is not correctly formatted, it could result in the source being displayed as "None". Ensure that each document in your knowledge base includes a properly formatted "source" key in its metadata.

3. Review Application Logs: The "Internal Server Error" suggests a server-side issue. Reviewing the application's logs can provide insights into what's causing this error when attempting to retrieve and display the source of a knowledge base answer. Look for any error messages or exceptions related to this process.

4. Codebase Examination: For a more in-depth analysis, consider examining specific parts of the codebase that handle the retrieval and display of knowledge base answer sources. Relevant files include knowledge_base_chat.py, basic_config.py.example, and kb_config.py.example within the Langchain-ChatGLM repository.

By following these steps, you should be able to identify and address the root cause of the issues you're experiencing. If you need further assistance or have more questions, feel free to ask.
