我正在试着做一个扫雷机器人，但是它似乎一直发送相同的错误。下面是代码：

const mineflayer = require('mineflayer')

const bot = mineflayer.createBot({
  host: 'localhost',
  port: ,
  username: 'Test_Bot'
})

下面是错误：

Error: Unsupported brand channel name

是否有任何方法可以修复此错误？
首先我尝试在我的世界里做一个局域网服务器，它发送了这个错误。然后我用online-mod创建了一个私人服务器：false，但它仍发送相同的错误。
