I want to create an MQTT conection based on Configuration module in my Nest.js app. I am using very old npm package: https://github.com/microud/nest-mqtt . I updated necessary dependencies and now I try to use it. However i am experiencing this issue:

Error: Nest cant resolve dependencies of the MQTT_OPTION_PROVIDER (?). Please make sure that the argument ConfigurationService at index [0] is available in the MqttModule context.

Here is how my app.module looks:

@Module({
  imports: [ConfigurationModule, MySQLModule, MQTTModule],
  controllers: [],
  providers: [],
})
export class AppModule {}

config.module.ts

@Module({
  imports: [ConfigModule.forRoot()],
  providers: [ConfigurationService],
  exports: [ConfigurationService],
})
export class ConfigurationModule {}

mqtt.module.ts

const MqttGlobalConnection = MqttModule.forRootAsync({
  useFactory: (config: ConfigurationService) => ({
    logger: {
      useValue: new CustomLogger('MQTT'),
    },
    ...config.MQTT_GLOBAL_CONNECTION,
  }),
  inject: [ConfigurationService],
  imports: [ConfigurationModule],
});

@Module({
  imports: [ConfigurationModule, MqttGlobalConnection],
})
export class MQTTModule {}

Is something incorrect in this pretty simple configuration or the error is in the nest-mqtt library.

PS
When i changed forRootAsync into forRoot everything seems to work, but looks a little bit worse in my opinion:

const MqttGlobalConnection = MqttModule.forRoot({
  logger: { useValue: new CustomLogger('MQTT') },
  ...new ConfigurationService(new ConfigService()).MQTT_GLOBAL_CONNECTION,
});
