nested exception is com.mongodb.CommandFailureException:

任何人都可以帮助我在调用控制台显示数据时在控制台中收到这些错误。

jdk = 1.8
mongodb = 3.6
spring = 4.x

这是控制器代码

public List<Product> searchProductWithAggregationWithPagination(Class<?> voName,String column,Integer currentPage,Integer noOfRecord) {

    List<Product> list1 = new ArrayList<Product>();
    try {
        GroupOperation groupByStateAndSumPop = group("productCode").
                first("id").as("id").
                first("productName").as("productName").
                first("description").as("description").
                first("productCode").as("productCode").
                first("eanCode").as("eanCode").
                first("categoryId").as("categoryId").
                first("subcategoryId").as("subcategoryId").
                first("productLineId").as("productLineId").
                first("brandId").as("brandId").
                first("mrp").as("mrp").
                first("discountedPrice").as("discountedPrice").
                first("consumerId").as("consumerId").
                first("status").as("status").
                first("createdDateTime").as("createdDateTime").
                first("attachmentId").as("attachmentId");

        MatchOperation matchStage = Aggregation.match(new Criteria("status").is(true));

        Aggregation agg = null;
        if(currentPage == 0 && noOfRecord == 0 && column.isEmpty()) {
            agg = newAggregation(groupByStateAndSumPop);
        }else {
            SortOperation sortByAvgPopAsc = sort(new Sort(Direction.DESC,column));
            agg = newAggregation(groupByStateAndSumPop
                    ,skip(currentPage),
                    limit(noOfRecord),matchStage,sortByAvgPopAsc);
        }

        AggregationResults<Product> result = mongoTemplate.aggregate(agg, Product.class, Product.class);

        list1 = result.getMappedResults();

    } catch (Exception e) {
        LOGGER.error(e);
    }
    return list1;
}

显示数据时MongoDB出错
