class Aws::ECS::Types::MissingVersionException
Amazon ECS
is unable to determine the current version of the Amazon ECS
container agent on the container instance and does not have enough information to proceed with an update. This could be because the agent running on the container instance is an older or custom version that does not use our version information.
