How to map SETOF Record postgreSQL

Hibernate ORM
1

I have a problem mapping a stored procedure returning a SETOF RECORDS.

This is the stored procedure

CREATE OR REPLACE FUNCTION plugin_statistic3.st_getoffline_period(
	_devid integer,
	_from timestamp without time zone,
	_to timestamp without time zone)
    RETURNS SETOF record 
    LANGUAGE 'plpgsql'
    COST 100
    VOLATILE PARALLEL UNSAFE
    ROWS 1000

AS $BODY$
DECLARE
     r RECORD;
     diff_interval INTERVAL; 
     v_ctr INTEGER = 0;
	 v_online BOOLEAN;
	 v_start TIMESTAMP;
	 v_end TIMESTAMP;
	 v_computeFirst TIMESTAMP;
	 v_totaloffline INTERVAL = '0';
	 v_offlineData RECORD;
   BEGIN
     FOR r IN
	 	SELECT * FROM plugin_statistic3.dblink('statisticserver', 'SELECT * FROM plugin_statistic3.statsdata_online
											   WHERE deviceid = ' || _devId ||
											   ' AND pointintime BETWEEN ''' || _from || '''' || ' AND ''' || _to || '''
											   ORDER BY pointintime DESC') AS(pointintime TIMESTAMP, deviceid INTEGER, online BOOLEAN)
		--WHERE deviceId = _devId
		--AND   pointintime BETWEEN _from AND _to
		--ORDER BY pointintime DESC
	LOOP
	    IF v_ctr = 0 THEN
		   v_online = r.online;
		   v_end = r.pointintime;
		   IF v_online = FALSE THEN
		      IF NOW() < _to THEN
			     v_computeFirst = NOW();
			  ELSE
			     v_computeFirst = _to;
			  END IF;
			  diff_interval = v_computeFirst - v_end;
			  v_offlineData := (r.pointintime, v_computeFirst, r.online, diff_interval);
 			  RAISE NOTICE 'Record % ', v_offlineData;           --v_offlineData,
			  RETURN NEXT v_offlineData;
		   END IF;
		END IF;
		RAISE NOTICE 'Pointintime % online %', r.pointintime, r.online;

		IF v_online != r.online THEN
		   IF v_online = TRUE THEN
		      diff_interval = v_end - r.pointintime;
			  RAISE NOTICE 'Period offline % ', diff_interval;
			  v_totaloffline = v_totaloffline + diff_interval;
			  v_offlineData := (r.pointintime, v_end, r.online, diff_interval);
 			  RAISE NOTICE 'Record % ', v_offlineData;           --v_offlineData,
			  RETURN NEXT v_offlineData;
            --(r.pointintime, r.online)::offlineData);
		   END IF;
		   v_end = r.pointintime;
		   v_online = r.online;
		END IF;
		v_ctr = v_ctr + 1;
	END LOOP;
	RAISE NOTICE 'Total period offline ============================> % ', v_totaloffline;
	
END;
$BODY$;

This is the mapped procedure

	@NamedStoredProcedureQuery(
		name = Config.getDeviceOfflinePeriod,
		procedureName = STDBConfig.STSchema + ".st_getoffline_period",
		parameters = {
				@StoredProcedureParameter (type = Integer.class, mode = ParameterMode.IN, name = Config.IN_deviceId),
				@StoredProcedureParameter (type = LocalDateTime.class, mode = ParameterMode.IN, name = Config.IN_fromPeriod),
				@StoredProcedureParameter (type = LocalDateTime.class, mode = ParameterMode.IN, name = Config.IN_toPeriod),
				@StoredProcedureParameter (type = Object[].class, mode = ParameterMode.OUT, name = Config.OUT_l)
				})

Running in pgAdmin works

SELECT * from plugin_statistic3.st_getoffline_period(809, '2021-01-01 00:00', '2021-01-11 22:00') as (a timestamp, b timestamp, c boolean, d interval);

This is the code to execute it

		StoredProcedureQuery procedureQuery = session
				.createNamedStoredProcedureQuery(Config.getDeviceOfflinePeriod)
				.setParameter(Config.IN_deviceId, deviceId)
				.setParameter(Config.IN_fromPeriod, from)
				.setParameter(Config.IN_toPeriod, to);
		procedureQuery.getResultList();

I had several errors depending on the call; tried also with procedureQuery.execute() and mapping also as REF_CURSOR.
With REF_CURSOR I have this exception:

javax.persistence.PersistenceException: org.hibernate.HibernateException: PostgreSQL supports only one REF_CURSOR parameter, but multiple were registered

With ParameterMode.OUT

engine.jdbc.spi.SqlExceptionHelper - ERROR: a column definition list is required for functions returning “record”

Any suggestion? Thanks in advance.
