How to send a notification when a pass is updated in Apple Wallet using Node.js?

Hi

I have integrated Apple Wallet into a Node.js application and added a pass to my wallet. Now, when I update the text in the pass, it gets reflected in the wallet, but I am not receiving any notifications about this update.

. When I set production: false, I get a success response, but the notification is not received on the phone.

. When I set production: true, I get a 'bad device token' error.

How can I send a notification to the phone when the pass is updated?
