无法根据位置流推文

Question

我正在使用Twit npm模块来流式传输特定位置的推文。如果我使用San Francisco，New York City之类的位置，效果很好，但是当我放置Kuala Lumpur或其他任何位置时，效果却不佳，并且出现错误：

错误：

Error: Bad Twitter streaming request: 406

代码：

var Twit = require('twit')
    var T = new Twit({
      consumer_key:         '...',
      consumer_secret:      '...',
      access_token:         '...',
      access_token_secret:  '...',
      timeout_ms:           60*10,  // optional HTTP request timeout to apply to all requests.
      strictSSL:            true,     // optional - requires SSL certificates to be valid.
    })

    var kualaLumpur = [ 3.1384803, 101.5470242, 3.139003, 101.686855 ]
    var stream = T.stream('statuses/filter', { locations: kualaLumpur })
    stream.on('tweet', function (tweet) {
      console.log(tweet)
    })
