Users in DescribeBroker payload is always empty for RabbitMQ

Confirm by changing [ ] to [x] below to ensure that it's a bug:

• I've gone though Developer Guide and API reference
• I've checked AWS Forums and StackOverflow for answers
• I've searched for previous similar issues and didn't find any solution

Describe the bug
Issue with MQ SDK/API - returns an empty list of users in DescribeBroker's payload if it's an AMQ instance with RabbitMQ engine.

Version of AWS SDK for Go?
v1.35.21

Version of Go (go version)?
go version go1.15.2 darwin/amd64

To Reproduce (observed behavior)

1. Create a new AmazonMQ with RabbitMQ as the engine and add a user.
2. Call DescribeBroker for that broker you created.
3. DescribeBroker returns an empty list in DescribeBrokerResponse.Users

Expected behavior
Users list should list the user I created.

Additional context
This issue does not occur with ApacheMQ engine.
Today AmazonMQ launched support for RabbitMQ as an engine.
I am trying to build it into terraform, but this issue causes some problems with the implementation: hashicorp/terraform-provider-aws#16030
I also see this issue in the CLI, boto3 and the AWS console. This is probably an API issue, but I can only open issues here.

I also opened a case in amazon support (case id 7577915821)

Hi @yardensachs,
Could you provide the trace logs of the call? Since this is a new feature it is probable that the sdk is not getting a response from the api call, which would make this a problem with the service (remember to remove sensitive info like credentials).
Here's an example on how to activate logging for service calls

[yardensachs]

The API is just not returning the user list really, its not an SDK issue. I opened a support ticket for AWS. I just thought opening here would make it faster to the AWS API team.

@KaibaLopez Should I be closing this?

@yardensachs ,
Yea, we only keep track of issues specific to the Go SDK here.

Hope it gets addressed soon

[yardensachs]

lol it did not, they said Users will always be empty with RabbitMQ as the engine, by design
