Solve the following python programming problem given the following code:
@ defer.inlineCallbacks 
def _create_request(self, destination, method, path_bytes, body_callback, headers_dict = { 
    
}, param_bytes = b'', query_bytes = b'', retry_on_dns_fail = True, timeout = None, long_retries = False) : 
    ' Creates and sends a request to the given url
        ' 
    headers_dict [b'User-Agent'] = [self.version_string] 
    headers_dict [b'Host'] = [destination] 
    url_bytes = self._create_url (destination, path_bytes, param_bytes, query_bytes) 
    txn_id = ('%s-O-%s' % (method, self._next_id)) 
    self._next_id = ((self._next_id + 1) % (sys.maxint - 1)) 
    outbound_logger.info ('{%s} [%s] Sending request: %s %s', txn_id, destination, method, url_bytes) 
    if long_retries : 
        retries_left = MAX_LONG_RETRIES 
else : 
        retries_left = MAX_SHORT_RETRIES 
http_url_bytes = urlparse.urlunparse (('', '', path_bytes, param_bytes, query_bytes, '')) 
    log_result = None 
    try : 
        while True : 
            producer = None 
            if body_callback : 
                producer = body_callback (method, http_url_bytes, headers_dict) 
try : 
                def send_request() : 
                    request_deferred = preserve_context_over_fn (self.agent.request, method, url_bytes, Headers (headers_dict), producer) 
                    return self.clock.time_bound_deferred (request_deferred, time_out = ((timeout / 1000.0) if timeout else 60)) 
response = (yield preserve_context_over_fn (send_request)) 
                log_result = ('%d %s' % (response.code, response.phrase)) 
                break 
except Exception as e : 
                if ((not retry_on_dns_fail) and isinstance (e, DNSLookupError)) : 
                    logger.warn ('DNS Lookup failed to %s with %s', destination, e) 
                    log_result = ('DNS Lookup failed to %s with %s' % (destination, e)) 
                    raise 
logger.warn ('{%s} Sending request failed to %s: %s %s: %s - %s', txn_id, destination, method, url_bytes, type (e).__name__, _flatten_response_never_received (e))...

    
    

    Fix the buggy line: log_result = ('%s - %s' % (type (e).__name__, _flatten_response_never_received (http_url_bytes)))
