Noticed::DeliveryMethods::Ios Error (Request failed {reason: unregistered, timestamp}

[NolanHovis]

I was working with ios push notifications with noticed (following Joe Masilotti's book instructions). I got it all setup and working with the bridge component for NotificationTokens. This worked like a charm, but stopped suddenly responding with:

Error performing Noticed::DeliveryMethods::Ios (Job ID: 52191e34-93c7-44f7-bbf6-a72a2bbbf20c) from Async(default) in 230.98ms: RuntimeError (Request failed {"reason"=>"Unregistered", "timestamp"=>1743716458628}):

The interesting thing about this is I opened my laptop and tested it there, and I was able to get notifications. I have a feeling this has something to do with APNs and not my Rails code. I have spent far too long trying to test this and wonder if anyone has run into the same issue. I haven't seen much about this response that has helped on Apple discussions.
Here is my Notifier for reference:

# To deliver this notification:
#
# NewMessageNotifier.with(record: @post, message: "New post").deliver(User.all)

class NewMessageNotifier < ApplicationNotifier
  required_param :message

  deliver_by :ios do |config|
    config.device_tokens = -> {
      recipient.notification_tokens.where(platform: "iOS").pluck(:token)
    }

    config.format = -> (apn) {
      apn.alert = "You have a new message!"
      apn.custom_payload = { path: params[:message].messageable.instance_of?(ChatGroup) ? chat_group_path(params[:message].messageable) : private_chat_path(params[:message].messageable) }
    }


    credentials = Rails.application.credentials.ios
    config.bundle_identifier = credentials.bundle_identifier
    config.key_id = credentials.key_id
    config.team_id = credentials.team_id
    config.apns_key = credentials.apns_key

    config.development = Rails.env.local?
  end

  notification_methods do 
    def body
      if params[:message].messageable.instance_of?(ChatGroup)
        "New message in #{params[:message].messageable.name}!"
      else
        "New message from #{recipient.name.titleize}!"
      end
    end
  end
end

Let me know if any more context is needed, thanks.

Hey @NolanHovis! I think you might have an invalid token in your database. If that happens, APNs will fail and cancel all future sends.

Make sure to implement the failure callback to delete invalid tokens. On the next send, this should remove that record from your database and the valid token will then work.
