Oracle ORDS GET handler with associative array as input parameter

Question

I would like to create a handler using http GET to invoke the following PL/SQL procedure

create or replace PROCEDURE test_array (
    ait_string   IN dbms_sql.varchar2_table,
    query_result out SYS_REFCURSOR
) as begin
delete  from v;
for k in 1..ait_string.count loop
insert into v values
    ( ait_string ( k ) );
    end
        loop;
    open query_result
    for select C from v;
end;
/

I attempted to create ORDS handler like that

I made the following request to test it

curl --location "https://<HOST>/ords/MY_ORDS_SCHEMA/test/test?ait_string=gjdklsjf"

and that error occurred

    "title": "User Defined Resource Error",
    "message": "The request could not be processed for a user defined resource",
    "o:errorCode": "ORDS-25001",

}

what would be the correct way to define the handler? Should value 'STRING' be used on call to define_parameter for the associate array parameter?
