Error message

Model '{model_id}' not found in model_list. Please check your config.yaml.

What it means

HTTPException(400) from the model-credential resolver: the router is initialized but get_deployment_credentials_with_provider returned no deployment for the requested model_id — the model is absent from config.yaml's model_list (or the id was mistyped), so no upstream credentials exist to use.
