Solutions

1. The smoke-validation response did not match the expected schema; verify the backend implements the expected API surface.
2. Update the response schema/validator or fix the backend output so required fields are present with correct types.
3. Confirm the configured model route matches the surface (e.g. openai/<model>) the validator expects.

When it happens

Trigger: Thrown at src/services/generation_backend_status_service.py:418 when the library encounters an invalid state.

Common situations: Reported when the generation backend smoke validation response JSON does not match the expected schema; occurs when the upstream returns an error payload or an incompatible response shape.
