+### Errors On Observe

+In some situations aws api returns an error in cases where the resource does not exist.
+It will be noticeable when the resource never gets created but you see an error from the api

+the `IsNotFound`-function of `zz_conversion.go`.
+
+To tell ack which error indicates that the resource is not present, add a similar config to `generator-config.yaml`:
