Дублирование событий подписки APN

Question

Я отправляю push-уведомление, используя node-apn NodeJS 8. Но я вижу, что push-уведомление отправляется один раз, а подписка на событие срабатывает несколько раз.Зависит от количества отправленных push-уведомлений. Похоже, что каждый раз, когда ti показывает на 1 строку меньше.

Вот вывод для 2 уведомлений:

TRANSMITTED: {"Type":"1","UserID":"XXX","Seq":0,"aps":{"sound":"CC.mp4","alert":"Test local push #0"}}, token 02565428df5c4ef480e48cdf85165334f03bc092a2f2445e867897ff0f3e0f34

Для 3 уведомлений это выглядит так:

TRANSMITTED: {"Seq":0,"aps":{"sound":"CC.mp4","alert":"Test local push #0"}}, token 02565428df5c4ef480e48cdf85165334f03bc092a2f2445e867897ff0f3e0f34

И аналогично для 4, 5 и т. Д. Количество нажатий.

Вот пример кода, который я использую для его воспроизведения (токен - фальшивка):

const apns = require('apn');
const path = require('path');

const certPath = path.resolve(__dirname, './config/cert/push/cert.pem');
const certKey = path.resolve(__dirname, './config/cert/push/key.pem');

var options = {
  gateway: 'gateway.sandbox.push.apple.com',
  cert: certPath,
  key: certKey,
  passphrase: 'FaKePaSs',
  ca: null,
  port: 2195,
  enhanced: true,
  maxConnections: 10,
  cacheLength: 10
};

const service = new apns.Connection(options);

service.on('transmitted', function(notification, device) {
  console.log('TRANSMITTED: '+ JSON.stringify(notification) +', token ' + device.token.toString('hex'));
});

service.on('transmissionError', function(errCode, notification, device) {
  console.log('ERROR: '+ JSON.stringify(notification) + ', token ' + device.token.toString('hex') + ', code: ' + errCode);
});

const notifications = [{
  payload: {"Seq": 0},
  alert: 'Test local push #',
  expiry: Math.floor(Date.now() / 1000) + 3600,
  sound: 'CC.mp4',
  token: '02565428df5c4ef480e48cdf85165334f03bc092a2f2445e867897ff0f3e0f34'
}, {
  payload: {"Seq": 0},
  alert: 'Test local push #',
  expiry: Math.floor(Date.now() / 1000) + 3600,
  sound: 'CC.mp4',
  token: '8fa1977a9eb648d4bc865900bcf85a76503acb7f4ded4eb284809167c3f8a902'
}, {
  payload: {"Seq": 0},
  alert: 'Test local push #',
  expiry: Math.floor(Date.now() / 1000) + 3600,
  sound: 'CC.mp4',
  token: '2d72933e029a4f5c92e49e74050296718c386b450645429fa1cdb13d16ded23c'
}];

notifications.forEach(function (n, i) {
  n.payload.Seq = i;
  n.alert = n.alert + i;

  const device = new apns.Device(n.token);
  const note = new apns.Notification();
  note.expiry = n.expiry;
  note.alert = n.alert;
  note.payload = n.payload;
  note.sound = n.sound;

  service.pushNotification(note, device);
});
