CometAPI reranking not supported

Error message

CometAPI reranking not supported: ${error}

What it means

CometAPI.rerank wraps any failure of the base rerank call with a 'reranking not supported' prefix. The actual cause (auth, missing /rerank endpoint on the proxied base URL, bad model) is in the appended message.

Solutions

1. Check the appended original message for the true failure.
2. Confirm the CometAPI base URL exposes a rerank endpoint and the model is rerank-capable.
3. Route reranking to a provider with native rerank support (Cohere, Jina, Bedrock).

try { await comet.rerank(body); } catch (e) { if (String(e).includes('reranking not supported')) return cohere.rerank(body); throw e; }

When it happens

Trigger: Calling rerank() on the CometAPI provider when the upstream /rerank request fails — e.g. the underlying OpenAI-compatible base URL has no rerank route.

Common situations: Aggregator proxies that only expose chat/embeddings; pointing the adapter at a base URL lacking Jina/Cohere-style /rerank endpoints.
