Summation of total amount using criteria builder and group concat

In my problem, I want to show the id and this particular id related key-value pair (x: date, y: sum of total price). But I don't get this result.

I am using sum, concat and group concat in criteriabuilder. But an error came that "Invalid use of group function". And I want that it will return the sum of every date present in database. Like there is only one data at a date then show the one if not then sum of all values. I am trying this,

Expression<String> grnCreatedAt = root.get("grnCreatedAt");
Expression<BigDecimal> itemPriceSum = criteriaBuilder.sum(grnItemJoin.get("totalAmount"));
Expression<String> itemPriceSumAsString = itemPriceSum.as(String.class);
// Construct the JSON structure
Expression<String> dataJson = criteriaBuilder.concat(criteriaBuilder.literal("{\"x\": \""),
         criteriaBuilder.concat(grnCreatedAt, criteriaBuilder.literal("\", \"y\": ")));
dataJson = criteriaBuilder.concat(dataJson,
               criteriaBuilder.concat(itemPriceSumAsString, criteriaBuilder.literal("}")));
Expression<String> groupConcat = criteriaBuilder.function("GROUP_CONCAT", String.class, dataJson);
Expression<String> data = criteriaBuilder.concat(criteriaBuilder.literal("["),
                    criteriaBuilder.concat(groupConcat, criteriaBuilder.literal("]")));


if (bumpRequest.getType().equalsIgnoreCase("grn")) {
                query.multiselect(grnStorageName.alias("grnStorageName"), data.alias("data"),
                        itemPriceSumAsString.alias("item_price"));
} else {
                query.multiselect(grnCostCenterDesc.alias("grnCostCenterDesc"), data.alias("data"),
                        itemPriceSumAsString.alias("item_price"));}

            query.where(criteriaBuilder.and(companyPredicate, branchPredicate, locationPredicate, datePredicate,
                    grnTypePredicate));
if (bumpRequest.getType.equalsIgnoreCase("grn")) {
                query.groupBy(groupByField, grnStorageName);
            } else {
                query.groupBy(groupByField, grnCostCenterDesc);
            }
            query.orderBy(criteriaBuilder.desc(itemPriceSumAsString));
