i try on fs_cli console by /event CUSTOM google_transcribe::transcription, it can return result,but

this.onceAsync('CUSTOM google_transcribe::transcription').then( function () {
util.log('google_transcribe');
});

this.event_json('CUSTOM google_transcribe::transcription');
it can't work

Please check https://github.com/shimaore/esl/issues/56#issuecomment-851045691#35
But basically you need to subscribe for the CUSTOM event then filter on the Event-Subclass.
