📄 Description

Summary

Add an automatic fallback path when the external document loader fails, so RAG processing can continue with the default loader behavior instead of hard-failing.

Why

External loader endpoints can be unavailable or transiently fail. This change improves resilience and keeps retrieval flows usable.

Changes

  • Add fallback logic from external loader to default loader path on failure.
  • Preserve existing behavior when external loader succeeds.

Validation

  • Verified branch fix/external-loader-auto-fallback contains the fallback commit and is pushed.
