Sometimes this method gives the Required result, But sometimes it gives either calorie null or Whole list Blank.

Hii,
I am using Fatsecret libraries for Search food with calories and servings of the food.
Here my code is:
public CustomResponse searchFoodItems(String query,Integer page) {
CustomResponse customResponse=null;
Response response = service.searchFoods(query,page);
//This response contains the list of food items at zeroth page for your query
SearchFoodDto searchFoodDto = new SearchFoodDto();
List searchFoods=new ArrayList();
try {
searchFoods = new ArrayList();
if(null!= response) {
int pageSize = response.getTotalResults()/response.getMaxResults();
searchFoodDto.setTotalPages(pageSize);
List compactFoods = response.getResults();
for (CompactFood compactFood :compactFoods) {
SearchFoodListDto searchFood=new SearchFoodListDto(); searchFood.setFoodName(compactFood.getName()); searchFood.setId(compactFood.getId()); searchFood.setType(compactFood.getType()); searchFoods.add(getFoodCalories(searchFood));
}
}
} catch (Exception e) {
e.printStackTrace();
}
searchFoodDto.setSearchFoodList(searchFoods);
customResponse=new CustomResponse<>(searchFoodDto,Status.SUCCESS);
return customResponse;
}
SearchFoodListDto getFoodCalories(SearchFoodListDto searchFoodListDto) {

	BigDecimal calories = BigDecimal.valueOf(0.0);
    try {
        Food food = service.getFood(searchFoodListDto.getId());
        if (null != food) {
        	for (Serving serving : food.getServings()) {     	  searchFoodListDto.setCalories(serving.getCalories());       		searchFoodListDto.setServing(Calculations.round(Double.valueOf(serving.getNumberOfUnits().toString()), 0)+serving.getMeasurementDescription());
        	}
        }
        else{
            searchFoodListDto.setCalories(calories);
        }
            
    } catch (Exception e) {
        e.printStackTrace();
    }
	return searchFoodListDto;
}

Sometimes this method gives the Required result.
But sometimes it gives either calorie null or Whole list Blank.

I am unable to fulfill my requirement.
Thanks,
Dhiraj
