Error in BedrockReranker.rerank: Unknown error occurred

Error message

Error in BedrockReranker.rerank: Unknown error occurred

What it means

Thrown when BedrockReranker.rerank catches a non-Error value (string throw, object rejection, symbol) from the AWS call. The original thrown value is discarded entirely, making this the least informative failure.

Solutions

1. Reproduce with logging around the SDK call to capture the raw rejected value (catch (e) { console.error(typeof e, e); }).
2. If caused by test mocks, make them reject with new Error(...) instead of strings.
3. Update or pin the AWS SDK version if middleware is the culprit.

catch (e) { if (!(e instanceof Error)) { log.raw('non-error rejection', e); throw new Error(String(e)); } }

When it happens

Trigger: A promise rejection with a plain object/string — e.g. an interceptor, mock, or SDK bug rejecting with a non-Error; serialization failures inside SDK middleware.

Common situations: Unit tests mocking the SDK with `throw 'oops'` instead of an Error; SDK middleware rejections; memory/serialization issues producing odd rejections.
