Why UnitOfWorkManager.Current in Domin Event Handlers is null?

Hi, I get UnitOfWorkManager.Current in my domain event handler and always it is null !! I need doing some transactional action in my event handler. I set also UnitOfWork attribute on my handler. what is the solution for my problem?

  [UnitOfWork]
  public void HandleEvent(EntityCreatedEventData<CustomerProfileChangeRequest> eventData)
  {
    // UnitOfWorkManager.Current is null here
  }
