Driver Error

I have this code:

import Homey from 'homey';
import mqtt from 'mqtt';

class MqttSmartBOB extends Homey.Driver {
  private devices: any[]; // Deklaracja właściwości devices
  private client: mqtt.MqttClient | null; // Deklaracja właściwości client

  constructor() {
    super();
    this.log('Initializing MqttSmartBOB driver');
    this.devices = []; // Inicjalizacja devices
    this.client = null; // Inicjalizacja client
  }

  /**
   * onInit is called when the driver is initialized.
   */
  async onInit() {
    this.log('MQTT Driver has been initialized');

    // Połączenie MQTT
    this.client = mqtt.connect('mqtts://something.eu.hivemq.cloud:8883', {
      username: 'log', // Zmień na swoje dane
      password: 'pass' // Zmień na swoje dane
    });

    // Obsługa połączenia
    this.client.on('connect', () => {
      this.log('MQTT connected');
      if (this.client) {
        this.client.subscribe('home/discover', (err) => {
          if (!err) {
            this.log('Subscribed to home/discover');
          } else {
            this.error('Failed to subscribe to home/discover:', err);
          }
        });
      }
    });

    // Obsługa błędów
    this.client.on('error', (err) => {
      this.error('MQTT error:', err);
    });

    // Obsługa zamknięcia
    this.client.on('close', () => {
      this.log('MQTT connection closed');
    });

    // Obsługa wiadomości
    this.client.on('message', (topic, message) => {
      this.log(`Received message on topic ${topic}: ${message.toString()}`);
      if (topic === 'home/discover') {
        let payload;
        try {
          payload = JSON.parse(message.toString());
        } catch (e) {
          this.error('Failed to parse message:', e);
          return;
        }
        this.log(`Received device discovery message: ${JSON.stringify(payload)}`);
        if (payload) {
          this.addDevice(payload);
        } else {
          this.error('Payload is undefined');
        }
      }
    });
  }

  async addDevice(payload: { id: string; name: string; type: string }) {
    try {
      const { id, name, type } = payload;
      this.log(`Attempting to add device with ID: ${id}, Name: ${name}, Type: ${type}`);

      // Sprawdzenie, czy urządzenie już istnieje
      const driverInstance = this.homey.drivers.getDriver('mqtt-driver');
      const devices = await driverInstance.getDevices();
      if (devices.some(device => device.getData().id === id)) {
        this.log(`Device ${id} already exists`);
        return;
      } else {
        this.devices.push({
          name: `${name}`,
          capabilities: ['measure_temperature'],
          icon: '/assets/thermometer-temperature.svg',
          data: {
            id: `${id}`,
          },
        });
        this.log(`Device ${id} added successfully`);
      }
    } catch (error) {
      // Rzutowanie error na Error
      if (error instanceof Error) {
        this.error(`Error adding device: ${error.message}`);
      } else {
        this.error(`Unexpected error: ${error}`);
      }
    }
  }

  /**
   * onPairListDevices is called when a user is adding a device and the 'list_devices' view is called.
   * This should return an array with the data of devices that are available for pairing.
   */
  async onPairListDevices() {
    return this.devices;
  }
}

module.exports = MqttSmartBOB;

When I compile have error:

 [err] [ManagerDrivers] Error Initializing Driver smartbob-mqtt: TypeError: Cannot read properties of undefined (reading 'discovery')
    at new Driver (/node_modules/@athombv/homey-apps-sdk-v3/lib/Driver.js:75:25)

    at /node_modules/@athombv/homey-apps-sdk-v3/manager/drivers.js:81:35
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

Where is problem?
