Node.js缓冲区+ lz4问题 - buffer.js：705抛出TypeError（＆＃39;值超出范围＆＃39;）

Question

我的node.js脚本中有以下行生成致命错误：

var compressedOutput = lz4.encode(new Buffer(logdata,"utf8"));

变量'logdata'包含我使用http请求参数创建的字符串。这是lz4的问题还是我创建缓冲区的方式？我怎么解决？错误信息如下：

    buffer.js:705
    throw TypeError('value is out of bounds');
          ^
TypeError: value is out of bounds
    at TypeError (<anonymous>)
    at checkInt (buffer.js:705:11)
    at Buffer.writeInt32LE (buffer.js:782:5)
    at Encoder._flush (/var/www/node_modules/lz4/lib/encoder_stream.js:210:7)

    at endWritable (_stream_writable.js:366:3)
    at Encoder.Writable.end (_stream_writable.js:344:5)

谢谢，非常感谢！
