Detailed description of a problem

I tried echo example program but it didn't work. It runs on raspberrypi 4. Bot connects to server and falls when i break block beneath him but when i type anything in chat he crashes instantly

Your current code

const mineflayer = require('mineflayer')

const bot = mineflayer.createBot({
  host: '192.168.0.11', // minecraft server ip
  username: 'bot', // minecraft username
  // password: '12345678' // minecraft password, comment out if you want to log into online-mode=false servers
  port: 4431,                // only set if you need a port that isn't 25565
  // version: false,             // only set if you need a specific version or snapshot (ie: "1.8.9" or "1.16.5"), otherwise it's set automatically
  // auth: 'mojang'              // only set if you need microsoft auth, then set this to 'microsoft'
})

bot.on('chat', (username, message) => {
  console.log('test')
  if (username === bot.username) return
  bot.chat(message)
})

// Log errors and kick reasons:
bot.on('kicked', console.log)
bot.on('error', console.log)

bot.on('kicked', console.log("Kicked"))
bot.on('error', console.log("Error"))

ur console.log was wrong-

[Gyanbu]

That part wasn't even ran, I copied it from example. I checked and it works for version 1.12.2 Is there some newer method to read chat from 1.19.2?

[AnyBananaGAME]

1.19.2 is not supported im pretty sure-
