Missing RequestId & HostId From mocked cognitoidp service API response

[filol]

This was using botocore at 1.34.7 and moto at 4.2.9

What Actually Happened

When I use moto to mock cognitoidp, I expected to see RequestId & HostId in the ResponseMetadata it's not the case actually.

Hi @filol, marking it as an enhancement to add these fields.

Do you have any documentation on the HostId-field? I couldn't find any info on the meaning/value of it.

Hi @bblommers, thanks !

Didn't find any information inside the boto3 documentation. Only a mention here : https://boto3.amazonaws.com/v1/documentation/api/latest/guide/error-handling.html#parsing-error-responses-and-catching-exceptions-from-aws-services

But i find this in the JAVA SDK documentation for S3 : "Amazon S3 also includes a host ID that can be provided to Amazon Web Services support when debugging an issue with Amazon S3."
https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/s3/S3ResponseMetadata.html

@filol
I just tested a range of CognitoIDP operations against AWS (admin_create_user, list_users, list_resource_servers, and a few others), and they all contain the RequestId-header. I'll probably refactor Moto a bit to return this field everywhere, not just for CognitoIDP, as I believe it is returned for all services.

However: none of these operations returned the HostId-header. Was there a specific operation where you saw that returned?

The RequestId will be part of every request from Moto v5.

We've released an alpha version yesterday if you want to try it out: moto==5.0.0alpha2
