SQL & PL/SQL :: ORA-00902 Invalid Data Type

I have created the following type

create or replace type type_sh_fld_rec
(
s_count count,
s_name varchar2(200),
e_date date);
/
create or replace type t_table_s_field as table of type_sh_fld_rec;
/

I have used these types in package pkg_shippers PROCEDURE process_shipments(userid);

when I run the following sql

select * from table(cast(DEV.PKG_SHIPPERS.process_shipments(324) AS T_TABLE_S_FIELD));

I get the following error.

ORA-00902 Invalid datatype.

I have tried to create the types and table from the sql prompt instead of the package spec, still no luck

Note: The sql statement works fine if I run it as schema owner but not as user who has all the privileges.
