Enable LangTrace for Improved Debugging and Request Tracing

[arturoliduena]

Description

LangTrace provides a UI to inspect requests/responses and significantly aids in debugging by reducing noise. At the moment, debugging requests and responses is cumbersome without a dedicated UI. While LangTrace was previously enabled, it was disabled due to a bug in the library, which has since been fixed.

This issue proposes re-enabling LangTrace to improve the debugging and tracing workflow for developers.

Steps to Enable LangTrace

1. Run LangTrace following the Docker setup instructions.
2. Uncomment the relevant initialization code in the file:
   init_langtrace.ts.
3. Start Kibana with the appropriate LangTrace environment variables:

   LANGTRACE_API_KEY=my_api_key LANGTRACE_API_HOST=http://localhost:3000 yarn start

Action Items

• Run and verify LangTrace setup using the provided instructions.
• Test functionality to ensure previously reported bugs in LangTrace are resolved.
• Validate that the debugging UI provided by LangTrace improves the developer experience.
• Add necessary documentation or guidelines for using LangTrace if re-enabled successfully.
