Solve the following python programming problem given the following code:
def _process_user_fields(me, conduit, args) : 
    d = { 
        
} 
    def process_user_field(name, param, add_me) : 
        d [name] = param 
        if add_me : 
            d [name].append (me) 
process_user_field ('authors', args.authors, args.author_me) 
    process_user_field ('reviewers', args.reviewers, args.reviewer_me) 
    process_user_field ('ccs', args.ccs, args.cc_me) 
    process_user_field ('subscribers', args.subscribers, args.subscriber_me) 
    process_user_field ('responsibleUsers', args.responsible_users, args.responsible_me) 
    user_phids = phlcon_user.UserPhidCache (conduit) 
    for users in d.itervalues () : 
        user_phids.add_hint_list (users) 
for key in d.iterkeys () : 
        d [key] = [user_phids.get_phid (d) for u in d [key]] 
return d 

    
    

    Fix the buggy line: d [key] = [user_phids.get_phid (d) for u in d [key]]

#Here is Python code to fix the buggy line: d [key] = [user_phids.

d [key] = [user_phids.get_phid (u) for u in d [key]]
