Solve the following python programming problem given the following code:
def _test(self, name, dp, method, args, request, reply, expected) : 
    print (('processing %s ...' % name)) 
    waiters = { 
        
} 
    dp.set_reply (reply, e) 
    if reply : 
        output = method (dp = dp, waiters = waiters, ** args) 
else : 
        output = method (dp = dp, ** args) 
request.serialize () 
    try : 
        eq_ (json.dumps (request.to_jsondict (), sort_keys = True), json.dumps (dp.request_msg.to_jsondict (), sort_keys = True)) 
except AssertionError as e : 
        json.dump (dp.request_msg.to_jsondict (), open ((('/tmp/' + name) + '_request.json'), 'w'), indent = 3, sort_keys = True) 
        raise e 
def _remove(d, names) : 
        def f(x) : 
            return _remove (x, names) 
if isinstance (d, list) : 
            return list (map (f, d)) 
if isinstance (d, dict) : 
            d2 = { 
                
} 
            for (k, v) in d.items () : 
                if (k in names) : 
                    continue 
d2 [k] = f (v) 
return d2 
return d 
expected = _remove (expected, ['len', 'length']) 
    output = _remove (output, ['len', 'length']) 
    try : 
        eq_ (json.dumps (expected, sort_keys = True), json.dumps (output, sort_keys = True)) 
except AssertionError as e : 
        json.dump (output, open ((('/tmp/' + name) + '_reply.json'), 'w'), indent = 4) 
        raise e 

    
    

    Fix the buggy line: dp.set_reply (reply, e)

#Here is Python program to fix the buggy line: dp.

dp.set_reply (reply, waiters)
