iOS Push Notification Error: {reason: 'TopicDisallowed'}

[iamromec]

Please read carefully before closing. I'm struggling to resolve notifications for more than a week and still it's half way resolved.

• I'm using the production certificate.
• It's working fine sometimes and suddenly starts throwing: { reason: 'TopicDisallowed' }
• It's working perfectly fine on localhost.
• It works fine sometimes on the server too (the issue is unstable). It automatically starts working and stops.

Here is the provider config:

const apn = require('@parse/node-apn'); // version: "@parse/node-apn": "^5.1.3"
const iosOptions = {
  token: {
    key: path.resolve('./lib/AuthK*********.p8'),
    keyId: '*********',
    teamId: '*******'
  },
  production: true
};

const apnProvider = new apn.Provider(iosOptions);

const apnNotification = new apn.Notification();
apnNotification.sound = 'default';
apnNotification.title = data.title;
apnNotification.body = data.message;
apnNotification.aps.threadId = threadId;
apnNotification.topic = topic;
apnNotification.payload = payload;
apnNotification.pushType = 'alert';
apnNotification.expiry = Math.floor(Date.now() / 1000) + 3600;

apnProvider.send(apnNotification, token)

Is there anything wrong with the config?

Error message: reason: 'TopicDisallowed'

PS: I dynamically change provider options to send notifications from multiple team IDs. Is there anything to do with provider.shutdown()? Because I'm not closing this.

As said, it suddenly starts throwing the error, not always. Please help if someone knows the solution.

Finally, I've resolved it by removing the package and writing a custom notification sender with Apple's official documentation for https://api.push.apple.com.
