I received the following warning message when I started Librechat:
warn: RAG API is either not running or not reachable at http://127.0.0.1:8000, you may experience errors with file uploads.
Then I decided to set up the RAG API. However, Librechat still couldn't connect to the RAG API. Additionally, when I attempted to access http://127.0.0.1:8000/ through my browser, I encountered the error message below:

2024-05-18 14:36:57,372 - root - INFO - Initialized embeddings of type: <class 'langchain_openai.embeddings.base.OpenAIEmbeddings'>
/home/user/LibreChat/rag_api/.venv/lib/python3.11/site-packages/langchain_community/vectorstores/pgvector.py:322: LangChainPendingDeprecationWarning: Please use JSONB instead of JSON for metadata. This change will allow for more efficient querying that involves filtering based on metadata.Please note that filtering operators have been changed when using JSOB metadata to be prefixed with a $ sign to avoid name collisions with columns. If you're using an existing database, you will need to create adb migration for your metadata column to be JSONB and update your queries to use the new operators.

The content of the .env file:

DB_HOST=xxx
POSTGRES_DB=xxx
POSTGRES_USER=xxx
POSTGRES_PASSWORD=xxx
RAG_OPENAI_API_KEY=xxx
JWT_SECRET=xxx

and I set RAG_API_URL=127.0.0.1:8000 in the .env file of Librechat. Is there something missing in my setup?

UPDATE: It did work when I set RAG_API_URL=http://127.0.0.1:8000 and I can chat with my documents.
