在for循环中发送时,没有在所有设备上接收到fcm推送通知

const sendNotification = (deviceId, userId) => {
  return new Promise((resolve, reject) => {
    let message = {
      notification: {
        title: 'TITLE',
        body: `notification is sent to ${userId}`
      }
    };
    let options = {
      contentAvailable: true,
      priority: "high",
      timeToLive: 60 * 60 * 24
    };
    firebase.messaging().sendToDevice(deviceId, message, options)
      .then(function (response) {
        resolve({
          message: `Successfully sent message`
        })
        console.log(`notification sent to ${userId}`);
      })
      .catch(function (error) {
        reject({
          message: "There is an issue sending push notification"
        })
        console.log('Error sending message:', error);
      });

  });
};
