Issue in Calling PostgreSQL function which returns REF_CURSOR using SimpleJdbcCall

I want to call a PostgreSQL function with put paramter as REF_CURSOR using SimpleJDBCCall. My function looks like below. I tried to call the function using the following JAVA code

CREATE OR REPLACE FUNCTION fnc_getdropdownlist(
p_reference_id numeric,
p_is_multiselect character,
p_source numeric)
RETURNS refcursor
   LANGUAGE 'plpgsql'
COST 100
VOLATILE 
AS $BODY$
DECLARE

    p_cursor_out   REFCURSOR;
    Lv_Errmsg      text;

BEGIN
    <-----function body----->
    RETURN p_cursor_out;
EXCEPTION
    WHEN OTHERS
    THEN RAISE;
END;

JAVA code

SimpleJdbcCall executor = new SimpleJdbcCall(jdbcTemplate)  
                .withFunctionName("fnc_getdropdownlist").withoutProcedureColumnMetaDataAccess()  
                .declareParameters(  
                        new SqlParameter("P_REFERENCE_ID", Types.INTEGER),  
                        new SqlParameter("P_IS_MULTISELECT", Types.VARCHAR),  
                        new SqlParameter("P_SOURCE", Types.INTEGER),  
                        new SqlOutParameter("results_cursor", Types.OTHER, new   GetDropDownListRowMapper()));  
        executor.compile();  
        SqlParameterSource param = new MapSqlParameterSource()  
                .addValue("P_REFERENCE_ID", 3)  
                .addValue("P_IS_MULTISELECT", "L")  
                .addValue("P_SOURCE", 7);  

        List<CodeDefinitionVO> simpleJdbcCallResult = executor.executeFunction(List.class,param);
        result = new LinkedHashMap<>();
            if(simpleJdbcCallResult !=null) {
                for (CodeDefinitionVO def : simpleJdbcCallResult) {
                    if (def.getId() == -1) {
                        result.put(null, def.getDescription());
                    } else {
                        result.put(def.getId(), def.getDescription());
                    }
                }

            }

Maven Dependency

<dependency>
        <groupId>org.postgresql</groupId>
        <artifactId>postgresql</artifactId>
        <version>42.3.5</version>
    </dependency>

Calling the function from postgreSQL console working fine but Running the above code I received an error message:

Is there a way to call the PostreSQL function which is returning a REF_CURSOR using SimpleJDBCCall? Thanks in advance
