Issue with 'aws cloudformation describe-events' command

Hello team,

When looking to view more details into a [pre-deployment validation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/validate-stack-deployments.html#validate-stack-deployments-cli), the following command syntax works:
`aws cloudformation describe-events --change-set-name `

However when providing the change set name, the following error occurs:
An error occurred (ValidationError) when calling the DescribeEvents operation: One of ChangeSetName, OperationId or StackName must be specified

Trying with the OperationId and StackName does not help either.
