For example, when making a managed cluster pygmy doesn't complain when you set the fallback_instances_scale_up argument to ["c6g.8xlarge,c6g.12xlarge"] instead of ["c6g.8xlarge","c6g.12xlarge"]. There obviously is no instance type "c6g.8xlarge,c6g.12xlarge", which pygmy should be able to detect and save you from you and your garbage request.
