public List<int>  Run([ActivityTrigger] IDurableActivityContext inputs, ILogger log)

                container = _repository.GetContainer();  
  
                var stores = container .Where(d =>  
                    d.CreatedDate >= _yesterday.Date && d.CreatedDate < _today.Date  
                ).ToList().DistinctBy(x => x.storeId).Select(s => s.storeId).ToList();  
  
                return stores;  
            }  
            catch (Exception ex)
