The Question
This issue-based on #16934
I just want to upgrade my instance type from instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.SMALL) to instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.LARGE), and not workable.
probably if I want to change to other different instance types, it maybe will show the same error messages too.
