AWS CloudTrail is an AWS service that helps you enable governance, compliance, and operational and risk auditing of your AWS account.

Actions taken by a user, role, or an AWS service are recorded as events in CloudTrail. Events include actions taken in the AWS Management Console, AWS Command Line Interface, and AWS SDKs and APIs.

The best place to check for error messages is in your cloud trail logs, which you can sort by date and time/user and many different other ways. These should help you find actions which create events logged and you should be able to get a better insight into their outcomes. To access them you need to navigate to your AWS console and search for Cloud Trail.
