In conformance with the BPMN 2.0 specification, a none intermediate event is a throwing event by default and cannot be configured as a catching event. A none intermediate event is typically used to show that some kind of event is thrown in the process, but is bypassed in the run time, similar to an abstract task.

A throwing none intermediate event does not actually throw anything. It has no associated flow service and no Process Engine implementation. As other none events (start and end), it has no generated wrapper service.
