在Android应用程序中,我使用FCM发送通知,云功能成功执行,如firebase控制台日志中所示,但在我的设备中它没有显示任何通知,可能是什么原因？

    if (senderUid == receiverUid) {
        //if sender is receiver, don't send notification
        promises.push(event.data.current.ref.remove());
        return Promise.all(promises);
    }
      console.log('notifying start3');
    const getInstanceIdPromise = admin.database().ref(`/users/${receiverUid}/accessToken`).once('value');
      console.log('notifying start4');
    const getReceiverUidPromise = admin.auth().getUser(receiverUid);
console.log('notifying start5');
    return Promise.all([getInstanceIdPromise, getReceiverUidPromise]).then(results => {
        const …
