Этот метод выдает ошибку при параллельном запуске 

Following  method : 

     @Override
            @Modifying(clearAutomatically = true)
            @Transactional
            public void updateCompletedTasksInfo(Task workHistoryTask) {
                long start = System.currentTimeMillis();
                logger.debug("Start updateCompletedTasksInfo() execution time {} ms", start);
                if (StringUtils.isNotBlank(workHistoryTask.getTaskId())) {
                    Task taskToUpdate = taskIngestionRepo.findByTaskIdAndWarehouseIdAndTenantId(
                            workHistoryTask.getTaskId(),
                            workHistoryTask.getTenantId(),
                            workHistoryTask.getWarehouseId());
                    if (taskToUpdate != null) {
                        taskToUpdate.setCompletedPriority(workHistoryTask.getCompletedPriority());
                        taskToUpdate.setCompletionTime(workHistoryTask.getCompletionTime());
                        taskToUpdate.setResourceId(workHistoryTask.getResourceId());
                        taskToUpdate.setDeviceCode(workHistoryTask.getDeviceCode());
                        taskToUpdate.setDestinationLocation(workHistoryTask.getDestinationLocation());
                        taskToUpdate.setDestinationLocationTravelSequence(workHistoryTask.getDestinationLocationTravelSequence());
                        taskToUpdate.setDestinationWorkZone(workHistoryTask.getDestinationWorkZone());
                        taskToUpdate.setDestinationWorkZoneTravelSequence(workHistoryTask.getDestinationWorkZoneTravelSequence());
                        if (workHistoryTask.getStartDateTime() != null) {
                            taskToUpdate.setStartDateTime(workHistoryTask.getStartDateTime());
                        }
                    } else {
                       logger.info("Task {} not found to perform update operation  for a warehouse_id {} :: ", workHistoryTask.getTaskId(), workHistoryTask.getWarehouseId());
                    }
                }
                long elapsedTime = System.currentTimeMillis() - start;
                logger.info(
                    "Method updateCompletedTasksInfo() for task {} and warehouse {} execution time {} ms ",
                    workHistoryTask.getTaskId(), workHistoryTask.getWarehouseId(), elapsedTime);
        }
