Error while trying to expire item programmatically

Question

I'm trying to expire an item using WWSBR_API.MODIFY_ITEM_POST_UPLOAD. The API doc states that parameter p_expiration should be in the format 'dd-mon-yyyy HH12:MI PM'. However whenever I try to use this format the procedure returns the error:
ORA-01830: date format picture ends before converting entire input string
ORA-06512: at "PORTAL.WWSBR_API", line 1209
ORA-06512: at "PORTAL.WWSBR_API", line 1361
ORA-06512: at line 12
Since WWSBR_API is wrapped there is no way to identify what is happening at line 1209 and 1361. Does anyone know how to correct this?
My test script is:
@set_context
declare
l_masterid      number := 33006;
l_id          number := 33007;
l_caid          number := 34;
l_folder_id     number := 32836;
l_region_id     number := 1060;
l_filename     varchar2(350) := 'DBFD5D42CE0109B0E034001083270748';
l_author     varchar2(30) := 'BATCHADM';
l_return     number;
begin
l_return := wwsbr_api.modify_item_post_upload(
p_master_item_id => l_masterid,
p_item_id => l_id,
p_caid => l_caid,
p_folder_id => l_folder_id,
p_region_id => l_region_id,
p_file_name => l_filename,
p_expire_mode => WWSBR_API.EXP_DATE,
p_display_name => 'EXPIRED',
p_description => 'This is an expired item.',
p_expiration => '09-JUN-2004 04:01 PM');
wwpro_api_invalidation.execute_cache_invalidation;
end;
