System information

My Subscriber

//Imports

type Injectables = {
    eventBusService: EventBusService;
   onboardingService: OnboardingService;
}

class MyProductSubscriber {
    private onboardingService: OnboardingService;

    constructor({ onboardingService, eventBusService }: Injectables) {
        this.onboardingService = onboardingService;
        eventBusService.subscribe('product:created', this.onProductCreated);

    }

    private onProductCreated = async ({id}) => {
        console.log('====================================');
        console.log('Product created', id);
        console.log('====================================');

        await this.onboardingService.testService({id})
    }

}

export default MyProductSubscriber;

OnboardingService

// imports

type InjectedDependencies = {
  manager: EntityManager;
  onboardingRepository: typeof OnboardingRepository;
};

class OnboardingService extends TransactionBaseService {
  protected onboardingRepository_: typeof OnboardingRepository;

  constructor({ onboardingRepository }: InjectedDependencies) {
    super(arguments[0]);

    this.onboardingRepository_ = onboardingRepository;
  }

  async retrieve(): Promise<OnboardingState | undefined> {
    const onboardingRepo = this.activeManager_.withRepository(
      this.onboardingRepository_
    );

    const status = await onboardingRepo.findOne({
      where: { id: Not(IsNull()) },
    });

    return status;
  }

  async testService({id}) {
    console.log("testService", id)

  }

  async update(data: UpdateOnboardingStateInput): Promise<OnboardingState> {
    return await this.atomicPhase_(
      async (transactionManager: EntityManager) => {
        const onboardingRepository = transactionManager.withRepository(
          this.onboardingRepository_
        );

        const status = await this.retrieve();

        for (const [key, value] of Object.entries(data)) {
          status[key] = value;
        }

        return await onboardingRepository.save(status);
      }
    );
  }
}

3. update variant

4. in console you will see

   error:   An error occurred while processing product-variant.updated: TypeError: Cannot read pr
   operties of undefined (reading 'onboardingService')
   

Expected behavior

Added Binding this.onProductCreated = this.onProductCreated.bind(this)

it worked
