Relace provider does not support embeddings.

Error message

Relace provider does not support embeddings.

What it means

Relace's adapter does not implement embeddings; embed() always throws 'Relace provider does not support embeddings.' Relace is purely an edit/completion provider.

Solutions

1. Use an embeddings provider (OpenAI, Jina, Voyage, etc.) for embed() calls
2. Fix the model→provider mapping so embedding models never resolve to Relace
3. Skip Relace in embedding-capable provider discovery

Example fix

// before
embeddingModel: { provider: 'relace', model: '...' }
// after
embeddingModel: { provider: 'openai', model: 'text-embedding-3-small' }

if (provider === 'relace') throw new Error('Relace cannot serve embeddings');

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

try { return await api.embed(body); } catch (e) { if (e.message.includes('does not support embeddings')) return await openai.embed(body); throw e; }

When it happens

Trigger: Calling embed() on a Relace adapter with EmbeddingCreateParams.

Common situations: Multi-provider setups where an embedding model accidentally resolves to the Relace provider; pipeline code calling embed() on every configured adapter.

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.
