AWS Bedrock rerank error (${(error as any).code}): ${error.m

Error message

AWS Bedrock rerank error (${(error as any).code}): ${error.message}

What it means

Thrown by BedrockReranker.rerank when the AWS SDK rejects the rerank request and the error carries an AWS-specific `code` field (e.g. AccessDeniedException, ThrottlingException, ValidationException). The SDK error code and message are wrapped into a plain Error with the 'AWS Bedrock rerank error' prefix. It always indicates a failed InvokeModel call to a rerank model such as amazon.rerank-v1.

Solutions

1. Check the (code) portion: AccessDeniedException -> fix IAM/credentials; ThrottlingException -> retry with backoff or request quota increase; ValidationException -> check numberOfResults/query size
2. Verify the rerank model ID (e.g. amazon.rerank-v1) is available and enabled in your configured AWS region
3. Confirm AWS credentials (AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY) and region are set and have bedrock:InvokeModel permission
4. Wrap rerank() calls in retry-with-exponential-backoff for transient ThrottlingException codes

Example fix

// before
const results = await bedrockReranker.rerank(query, chunks);
// after
const results = await withRetry(
  () => bedrockReranker.rerank(query, chunks),
  { retries: 3, onRetry: (e) => !/Throttling|TooMany/.test(e.message) }
);

function isAwsCodedError(e: unknown): e is Error & { code: string } {
  return e instanceof Error && 'code' in e;
}

try {
  const scores = await reranker.rerank(query, chunks);
} catch (e) {
  if (e instanceof Error && /AWS Bedrock rerank error \((Throttling|TooManyRequests)/.test(e.message)) {
    await backoff(); // retry
  } else throw e;
}

When it happens

Trigger: Calling rerank() with an invalid AWS key/secret (AccessDeniedException / UnrecognizedClientException), a model the account has no access to, a malformed rerank request payload (ValidationException), missing aws region config, or hitting Bedrock throttling limits (TooManyRequestsException / ThrottlingException).

Common situations: Wrong or expired AWS credentials in env, IAM user without bedrock:InvokeModel permission, using a rerank model not enabled in the given region, exceeding TPS quotas, or a modelId typo.
