I have followed this [blog ](https://aws.amazon.com/blogs/architecture/field-notes-enroll-existing-aws-accounts-into-aws-control-tower/)to enroll existing AWS accounts into AWS ControlTower to the nested OU's, But it's failing with error message like below Error message: InvalidParametersException The parent organizational unit 'ou-xxxxxxxxxx' is not enrolled in AWS Control Tower. Nested OU registered under Control Tower but still posting the error message.
