Sending Push Notification To Apple Watch Does not work

[remiroz]

I am building node.js back-end to send push notifications to Apple Watch.

"apn": "^2.2.0", "node": "20.11.1"

This is how I send notification to watch.

const settings = {
  apn: {
    token: {
      key: "./key.p8",
      keyId: process.env.APPLE_KEY_ID,
      teamId: process.env.APPLE_TEAM_ID,
    },
    production: true,
  },
};

const push = new PushNotifications(settings);

const registrationIds = [
  "128a2827cf9d3af2c08b435bfc0fb5264fb4d3a80a7f0f2a7fe79ec2769f978d",
  "fea34620baeeb8bae19147484497a5c6607395e83a36ba8d568ac27f3fd49890",
];

const data = {
  topic: process.env.APPLE_BUNDLE_ID,
  body: "Powered by Sender",
  custom: {
    sender: "Sender",
  },
  priority: "high",
  contentAvailable: true,
  retries: 1,
  badge: 2,
  sound: "ping.aiff",
  alert: {
    title: "Test Title",
    body: "Test Body",
  },
  silent: false,
  truncateAtWordEnd: true,
  mutableContent: 0,
  expiry: Math.floor(Date.now() / 1000) + 28 * 86400,
  timeToLive: 28 * 86400,
};

push
  .send(registrationIds, data)
  .then((results) => {
    return res.send({ results });
  })
  .catch((err) => {
    res.status(500).json({ err });
  });

FYI, the key file is in the right place and the .env file contains all env credentials including Key_id, Team_id and Bundle_id.

I tried to call this endpoint using Postman and got this response.

However, the watch never received a notification even though the it returned a success status to me.

I wonder if there is something wrong with code.

Can anyone help me with this?

Thanks in advance!
