SQL & PL/SQL

Heres a simple version of my plsql code using bulk collect merge and object

I keep getting invalid cursor.

How do I debug this invalid cursor that uses object??

I run the sql in the cursor it returns me a legit result sets.

--drop table emp
--drop table new_emp
create table emp as select object_id as empno, object_name as ename from user_objects; 
select max(length(object_name)) from user_objects
select count(*) from emp
create table new_emp as select * from emp where 1 = 0
 create or replace type myScalarType as object 
 ( empno number, ename varchar2(300) ) 
--drop type myTableType
 create or replace type myTableType as table of myScalarType 
--delete from emp
--delete from new_emp
select * from new_emp
select * from emp
declare 
 l_data myTableType; 
 l_limit number default 5; 
 lv_row_cnt number := 0;
 cursor c is select myScalarType(empno,ename) from emp; 
 begin 
 open c; 
 loop 
 fetch c bulk collect into l_data limit l_limit; 
 if ( l_data.count > 0 ) 
 then 
 --for i in 1 .. l_data.count 
 --loop 
 --l_data(i).ename := initcap( l_data(i).ename ); 
 --end loop; 
 merge into new_emp 
 using ( select * from table(cast(l_data as myTableType))) X 
 on (new_emp.empno = x.empno) 
 when matched then update set ename = x.ename 
 when not matched then insert ( empno, ename ) values ( x.empno, x.ename ); 
 end if; 
 exit when c%notfound; 
 dbms_output.put_line('commit '||to_char(systimestamp));
 dbms_output.put_line('l_data.count '||l_data.count);
select count(*) into lv_row_cnt from new_emp;
 dbms_output.put_line('lv_row_cnt '||lv_row_cnt);
 commit;
 end loop; 
 dbms_output.put_line('commitxx '||to_char(systimestamp));
 dbms_output.put_line('l_data.countxx '||l_data.count);
select count(*) into lv_row_cnt from new_emp;
 dbms_output.put_line('lv_row_cntxx '||lv_row_cnt);
 end;
