Model not found for type .

Error message

Model {model_name} not found for type {model_type_val}.

What it means

LookupError raised in name-based id resolution when the provider and instance resolved fine but TenantModelService.get_by_provider_id_and_instance_id_and_model_type_and_model_name found no tenant_model row for the pure model name under that provider+instance with that model_type. All three keys (provider, instance, model_type, model name) must match a registered row.

Solutions

  1. Open Model Providers, expand the provider, and confirm the model is listed with the exact name; re-add it if missing.
  2. Check the requested model_type matches how the model was added (e.g. an embedding-only entry will not resolve for CHAT).
  3. Re-copy the full 'model@provider' string from the UI selector into your config.
  4. Query tenant_model by provider_id and instance_id to see the exact stored names.
Defensive patterns

Strategy: try-catch

Validate before calling

provider = TenantModelProviderService.get_by_tenant_id_and_provider_name(tenant_id, provider_name)
instance = _resolve_instance_for_model(provider, instance_name, model_name)
if not TenantModelService.get_by_provider_id_and_instance_id_and_model_type_and_model_name(
        provider.id, instance.id, model_type.value, pure_name):
    raise ValueError(f"Model '{pure_name}' not registered under {provider_name}")

Try / catch

try:
    model_id = get_model_id_from_name(tenant_id, model_type, model_name)
except LookupError as e:
    if "not found for type" in str(e):
        # permanent: name/registration mismatch, no retry
        raise

Prevention

When it happens

Trigger: Resolving 'some-model@Provider' where 'some-model' was never added under that provider for this tenant; the model was added under a different model_type than requested (embedding vs chat); the model name has a typo or the provider's model list changed and the row was removed.

Common situations: Custom/self-hosted models added with a slightly different name ('qwen2.5-7b' vs 'Qwen2.5-7B'); requesting a type the row does not carry so the type-filtered query returns empty; stale names in old DSL after model re-registration.
