получение ошибки CallableStatementCallback; плохая грамматика SQL при вызове процедуры из postgreSQL

Я использую Spring-JDBC Support и PostgreSQL и получаю сообщение об ошибке. Я могу запустить процесс из бэкенда. Итак, он скомпилирован.

CREATE OR REPLACE PACKAGE schemaname.my_pkg_name
IS
PROCEDURE update_email(person_id numeric, OUT email_gratitude_id numeric);
END my_pkg_name;

CREATE OR REPLACE PACKAGE BODY schemaname.my_pkg_name
IS
PROCEDURE update_email(person_id numeric, OUT email_gratitude_id numeric) IS

begin
select email_gratitude_id into email_gratitude_id from schemaname.emp_email_dtls_tbl
where person_id=person_id;

end;
END my_pkg_name

private class EmployeeSP extends StoredProcedure
{ 
    private static final String SPROC_NAME = "schemaname.my_pkg_name.update_email"; 

    public EmployeeSP( DataSource datasource )
    { 
        super( datasource, SPROC_NAME );                    
        declareParameter( new SqlParameter("person_id", Types.INTEGER) );           
        declareParameter( new SqlOutParameter("email_gratitude_id", Types.INTEGER ) ); 

        compile();
    }

    public Object execute(int emp_id)
    { 
        Map<String,Object> results = super.execute(emp_id,null); 
        return results.get("email_gratitude_id"); 

    }
};


EmployeeSP tp = new EmployeeSP(template.getDataSource());
tp.execute(123456);
