Facing issue with JDEdwards setup in AWS

Hi, This is my first time using AWS and I am trying to setup JDEdwards EnterpriseOne on AWS referring to the link - https://medium.com/@nwosuonyedikachi/how-to-setup-jd-edwards-on-aws-step-by-step-25b9704be8df#:~:text=How%20to%20Setup%20JD%20Edwards%20on%20AWS%20%E2%80%94,Application%20Interface%20Server%20%28AIS%29%20server%20on%20port%208180.

I have logged into AWS-> Navigated to EC2 -> Launch Instances -> Choose AMI -> searched "jd edwards" and selected 9.2.6 version from AWS MarketPlace. Currently, I am blocked at the step since I am getting an error saying - The AMI ID (ami-xxxxxxxxxxxxx) is not valid. The AMI may no longer exist or may be specific to another account or region.

Need help in understanding this issue and fixing this to proceed further with the setup. Please let me know if it is an issue with AWS permissions. If so, what permissions are missing. Thanks in advance.
