S3 eventbridge objects

Serverless Framework
1

I have a serverless lambda set up to listen to eventbridge, and per the docs it’s using CloudTrail to get the event:

events: [
    {
      eventBridge: {
        pattern: {
          source: ['aws.s3'],
          'detail-type': ['AWS API Call via CloudTrail'],
          detail: {
            eventSource: ['s3.amazonaws.com'],
            eventName: ['PutObject'],
            requestParameters: {
              bucketName: ['mybucket']
            }
          }
        }
      }
    }
  ]

the problem is that the event object isn’t what I’m expecting, I was expecting EventBridge event message structure - Amazon Simple Storage Service which includes the details object that will contain metadata. I’m epecting an object that looks like this example
