  # An Error is an all-purpose object that represents a failure in the
  # performance of an Action. Errors are present in failure Results.
  #
  # Error contains a code, which is a machine-friendly unique key that
  # represents the type of error returned. Error also contain a message, which
  # is the human-readable text explaining the particular failure that happened.
  # Optinally Error might also have an attribute value, which is the attribute
  # that caused the failure, in case the error was originated from an Input.
