Solutions

1. Check the generation backend's smoke-test response: it did not return valid JSON.
2. Verify the backend endpoint, model name, and API key so the smoke request succeeds.
3. Inspect backend logs for errors returned as plain text or HTML instead of JSON.

When it happens

Trigger: Thrown at src/services/generation_backend_status_service.py:409 when the library encounters an invalid state.

Common situations: Reported when the generation backend smoke validation returns a body that is not valid JSON; occurs when the configured endpoint is not an OpenAI-compatible server or is intercepted by a proxy.
