Relace provider does not support model listing.

Error message

Relace provider does not support model listing.

What it means

Relace's adapter does not implement model listing; list() always throws 'Relace provider does not support model listing.' Model ids must be known/configured statically.

Solutions

1. Catch and skip Relace when aggregating model lists
2. Configure Relace model ids statically (e.g. relace-v1) in your config
3. Filter non-listable providers out of discovery

Example fix

// before
const models = await adapter.list();
// after
const models = await adapter.list().catch(() => []);

const listable = provider !== 'relace';

const supportsList = (p: string) => p !== 'relace';

const models = await api.list().catch(() => []);

When it happens

Trigger: Calling list() on a Relace adapter, typically during model discovery across providers.

Common situations: Model-picker UIs or /models aggregation endpoints that call list() on every adapter; the Relace call throws and breaks enumeration unless caught.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
