iOS 11의 자동 푸시 알림이 무시되었습니다.

Question

iOS 11에서 자동 알림 푸시 알림 (배지/소리/알림 없음)을 보내고 콘텐츠를 사용할 수없는 경우 알림이 무시되고 앱으로 전달되지 않습니다.

<Error>: Ignoring notification with no alert, sound or badge (it.my.app.dev): C146-3838 

그리고 더 완전한 : :이 또한 작동이 도착할 때 소리를 재생하지 않습니다

은

{ 
    "aps" : { 
     "content-available" : 1, 
    }, 
    "type" : "0" 
} 

장치 로그가 통지입니다 :

{ 
    aps = { 
     "content-available" : 1, 
     sound : "" 
    }; 
}
