I'm encountering an unexpected error when subscribing to realtime database changes and I couldn't find anything about it on the web.

...
final supabase = Supabase.instance;
...

class User {
  String uid;
  late final RealtimeSubscription subscription;

  User({required this.uid}) {
    subscription = supabase.client.from("profiles:id=eq.$uid").on(SupabaseEventTypes.update, (data) {
      stdout.writeln("Updating user $uid");
    });
  }
}

The subscription works flawlessly for the first ~30 seconds but then stops working with the following error:
