(RAG System) Fix for the PPTX-Upload Bug

[fbaeumer]

Fix for PPTX File Handling in RAG System

Issue

Some users are experiencing issues with the RAG system not correctly processing PPTX files (e.g., #2462).

Root Cause

The problem stems from the RAG system being started as Docker-Lite, which uses requirements.lite.txt. This file doesn't include the python-pptx==0.6.23 package, which is present in the full requirements.txt.

Solution

Manually installing the python-pptx package in the Docker container resolves the issue. However, a more permanent solution is to modify the docker-compose.yml file in LibreChat.

Proposed Change

Update the rag_api section in docker-compose.yml:

yaml
rag_api:
  container_name: rag_api
  image: ghcr.io/danny-avila/librechat-rag-api-dev:latest
  environment:
    - DB_HOST=vectordb
    - RAG_PORT=${RAG_PORT:-8000}
  restart: always
  depends_on:
    - vectordb
  env_file:
    - .env

After making this change, run:

docker-compose pull

Question for Maintainers

@danny-avila Is this issue already known? If not, would you consider implementing this fix?

Thank you for your attention to this matter.

Best regards,
