Cloudtrail for CreateCapacityProvider returns asg name instead of arn in [requestParameters][autoScalingGroupProvider][autoScalingGroupArn] when you create ecs cluster with default capcity provider

Hi, So I was working with the cloudtrail event CreateCapacityProvider, And when you manually create capacityprovider it return capacity provider arn perfectly in [requestParameters][autoScalingGroupProvider][autoScalingGroupArn] . But when you create new ecs cluster with default capcity provider of ec2, in json response you will get asg name . There is easy workaround , of just looking at responseElements instead of requestParameter, But thought of informing to the community so aws can fix this.

How to recreate this issue?

Create new ecs cluster with ec2 instance, and select to create new asg from ecs portal itself, And check cloudtrail for CreateCapacityProvider event
