AWS Bedrock Runtime - token count - requestId

[agustinp93]

Hello!

My team is using @aws-sdk/client-bedrock-runtime and everything is working fine but we are missing metadata that is visible in other SDK's.

We are using:

• AWS Lambda
• Node: version 20
• Bedrock: @aws-sdk/client-bedrock-runtime "^3.529.1"
• modelId: "anthropic.claude-instant-v1", (any version we tried does not have the token count)

Request is based in this example: https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-runtime_example_bedrock-runtime_InvokeClaude_section.html

In the response we don't receive the token count of the request and response done to Bedrock:
metadata { httpStatusCode: 200, requestId: '########-####-####-####-#########', extendedRequestId: undefined, cfId: undefined, attempts: 1, totalRetryDelay: 0 }

I can see in the docs that other SDK like PHP do return headers in the response and the token count is one of them. I also saw them while doing requests from a React app. But in this scenario where we moved to a lambda to be able to collect large amounts of data before invoking Bedrock this metadata we need is missing.

I'm missing something in the request config? is a bug we need to report?

Thanks
