What is your problem?

The problem occurs when trying to enable notifications for a characteristic. In the example app, it works fine, but in my own app, where I'm using a provider with Riverpod, it doesn't work and I get the following error:

CCCD descriptor for characteristic not found This is my code.

Future<void> connectToDevice(BluetoothDevice device) async {
    try {
      await device.connect(mtu: null);
      // state = device;
      final services = await device.discoverServices();

      for (var service in services) {
        for (var char in service.characteristics) {
          if (char.uuid.uuid == "0000ffe4-0000-1000-8000-00805f9a34fb") {
            print(char.descriptors);
            char.lastValueStream.listen((event) {
              print(event);
            });
            await char.setNotifyValue(true);
          }
        }
      }
    } catch (e) {
      // Manejar el error
      await device.disconnect(queue: false);
      print('Error al conectar: $e');
      throw Exception();
    }

In prints show like the descriptor exist buy when i try to connect throw this
