OpenRAG Version

Deployment Method

Operating System

macOS 26.2

Python Version

3.13.11

Affected Area

Ingestion (document processing, upload, Docling)

Bug Description

I tried to ingest a document, it took a long time and eventually failed. The message for the failed document says:

Ingestion failed: Server error '500 Internal Server Error' for url 'http://langflow:7860/api/v1/run/5488df7c-b93f-4f87-a446-
b67028bc0813' For more information check: https:// developer.mozilla.org/en-US/docs/Web/HTTP/Status/500

Linking to MDN for docs on 500 errors is not a useful error message.

Steps to Reproduce

1. Try to upload a document for ingestion
2. It fails (not sure why)

Expected Behavior

An error message that tells me why it failed.

Actual Behavior

A generic 500 error message that I don't know where it came from.

Relevant Logs

Screenshots

Additional Context

I found it hard to get anything out of the logs due to #819.
