So I'm using the X-Ray SDK in a NodeJS Lambda with AWS SDK v3 as you describe in this post. I've wrapped both the DynamoDB and SQS clients with `AWSXRay.captureAWSv3Client()`, but the traces for SQS and DynamoDB aren't showing up in the service map in the Lambda console for my function. It's as if they aren't getting the subsegment from X-Ray. Any thoughts on this?
