Do you need to file an issue?

• I have searched the existing issues and this bug is not already filed.
• My model is hosted on OpenAI or Azure. If not, please look at the "model providers" issue and don't file a new one here.
• I believe this is a legitimate bug, not just a question. If this is a question, please use the Discussions area.

Describe the issue

as title mentioned, log.json not updated its results over time.

This significantly hampers debugging and tracking the status and error messages of the index. Additionally, could a complete date and timestamp be added to the indexing-engine.log? Could a timestamp also be added to

logs.json?

Steps to reproduce

running index procedure

The issue arises because the overall runtime is too long, and I want to see detailed error messages and content. However, I noticed that logs.json does not update its content in real time.

The logs in indexing-engine.log provide much more detail than logs.json, and will update as the system progresses.
