I am getting above error when trying to get retrieving information. I am using the following URL: http://localhost:9000/agency/search/findAgencyByZip?zip=02019. And the table structure is attached in the issue, database used is oracle. Query is as below in the AgencyRepository.

interface AgencyRepository … {

  @Query("SELECT DISTINCT a, l.contactInfo.address.city, l.contactInfo.address.street, l.contactInfo.phone from Agency a, Location l INNER JOIN  l.zips z where a.ceID = l.agencyCode and z.zipCode = :zip")
  public List<Agency> findAgencyByZip(@Param("zip") String zip);
}
