I am using `SpringBoot` with `JPA` and `QueryDSL`. I have written a `HQL` to fetch some custom records from the table but it is throwing `Exception`. Below I am mentioning code of repository:

```
@Repository
public interface LoanOfferRepository extends JpaRepository<LoanOffer, Long>, QuerydslPredicateExecutor<LoanOffer> {

    @Query("select lo.startDate,count(*) from LoanOffer lo where lo.loan.fsp= :fsp and lo.startDate between :fromDate and :toDate Group by lo.startDate")
    public Map<LocalDate,Integer> getLastMonthLoans(@Param("fsp")Fsp fsp,@Param("fromDate")LocalDate fromDate,@Param("toDate")LocalDate toDate);
}

```

Whenever I call this method `getLastMonthLoans()` I am getting following exception:

```
Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.dao.IncorrectResultSizeDataAccessException: query did not return a unique result: 9; nested exception is javax.persistence.NonUniqueResultException: query did not return a unique result: 9] with root cause

javax.persistence.NonUniqueResultException: query did not return a unique result: 9

```

Is there anything wrong with code or Query or Return type ? Query seems to work fine though.
