Solutions

1. Set VISION_MODEL to a non-Hermes route (e.g. a standard openai/<model> route) for image extraction.
2. Pick a verified vision-capable model that does not route through a Hermes deployment.
3. Update .env and restart after changing VISION_MODEL.

When it happens

Trigger: Thrown at src/services/image_stock_extractor.py:278 when the library encounters an invalid state.

Common situations: Raised when VISION_MODEL is routed to an unverified Hermes deployment; occurs when the configured vision route includes a Hermes backend that has not passed verification.
