Prepare stage failing while trying to change the Audit account email address about landing-zone-accelerator-on-aws HOT 3 OPEN

While I was trying to change the email address for Dev Account. I got following error at Prepare Stage

from landing-zone-accelerator-on-aws.

You must be logged in with the root user to change an AWS account email address (https://docs.aws.amazon.com/IAM/latest/UserGuide/root-user-tasks.html)

Cannot change it via LZA by just updating accounts-config.yaml.

Thank You Erik.

Once I change AWS account email by login as root user. Do I still have to update email address on accounts-config.yaml? Or running the [AWSAccelerator-Installer] and [AWSAccelerator-Pipeline] pipeline will fix the accounts-config.yaml. Another question is do I need to change email in Service Catalog as mention on

https://docs.aws.amazon.com/controltower/latest/userguide/change-account-email.html

"Update the provisioned product in Service Catalog using the email address that previously belonged to the account. The process for updating the provisioned product includes associating the new email address with the provisioned product. This way the email address change takes effect in AWS Control Tower. "
