ExportServerEngineAttribute - AWS OpsWorks CM

This operation is synchronous.

A ValidationException is raised when parameters of the request are not valid. A ResourceNotFoundException is thrown when the server does not exist. An InvalidStateException is thrown when the server is in any of the following states: CREATING, TERMINATED, FAILED or DELETING.
