Node-Cron Does Not Working On Heroku (Push Scheduled Notification)- Node Cron Not Execute On Heroku Server

Question

I am trying to send a scheduled notification with the node-cron library and it is working fine in my local system but after deploying the codes to the Heroku server it is not working.

const triggerPushNotification = (notifiction, startMinutes, startHour) => {
  console.log('Checked Trigger Push Notification Function ...');

  cron.schedule(`${startMinutes} ${startHour} * * *`, async () => {
    console.log('Checked Inner Cron ...');

    await notificationHelper.pushNotification(notifiction.receiversTokens, notifiction.notificationTitle, notifiction.notificationBody, notifiction.notificationURL, notifiction.notificationImage);
  });
};

cron.schedule('*/55 * * * * *', async () => {
  console.log('Checked Outer Cron ...');

  const notifiction = await notificationHelper.viewScheduledNotification();
  const formattedStartDate = `${notifiction.startDate}`;
  const formattedEndtDate = `${notifiction.endDate}`;

  const fullTodayDate = new Date();
  const fullEndDate = new Date(formattedEndtDate);
  const fullStartDate = new Date(formattedStartDate);

  const startHour = notifiction.time.split(':')[0];
  const startMinutes = notifiction.time.split(':')[1];

  if (fullStartDate <= fullTodayDate && fullTodayDate <= fullEndDate) {
    console.log('Checked Middle Cron ...');
    console.log(startHour, ':', startMinutes);
    triggerPushNotification(notifiction, startMinutes, startHour);
  }
});
