Detailed description of a problem

A clear and concise description of what the problem is, with as much context as possible. What are you building? What problem are you trying to solve?

I am building a pathfinding bot with Mineflayer viewer.

What did you try yet?

I am not sure what to try because I don't know what the problem is (vague error) Did you try any method from the API? n/a Did you try any example? Any error from those? n/a, unique issue

Your current code

const mineflayer = require('mineflayer')
const { mineflayer: mineflayerViewer } = require('prismarine-viewer')
const { pathfinder, Movements, goals: { GoalNearXZ } } = require('mineflayer-pathfinder')

const bot = mineflayer.createBot({
    host: '192.168.1.87',
    port: '25571',
    username: 'firefox',
})

bot.loadPlugin(pathfinder)

bot.once('spawn', () => {
  mineflayerViewer(bot, { port: 3007, firstPerson: false })
  const mcData = require('minecraft-data')(bot.version)
  const defaultMove = new Movements(bot, mcData)
  bot.pathfinder.setMovements(defaultMove)
  function getRandomInt(max) {
    return Math.floor(Math.random() * max);
  }
  var random = [getRandomInt(6553), getRandomInt(6553)]
  console.log(`Moving to X ${random[0]}, Z ${random[1]}`)
  bot.pathfinder.setGoal(new GoalNearXZ(random[0], random[1], 1))
})

bot.on('kicked', console.log)
bot.on('error', console.log)
bot.on('end', console.log)

Expected behavior

The bot is able to stay as long as it likes

Observed behaviour

Error: write ECONNRESET at afterWriteDispatched (node:internal/stream_base_commons:160:15) at writeGeneric (node:internal/stream_base_commons:151:3) at Socket._writeGeneric (node:net:769:11) at Socket._write (node:net:781:8) at writeOrBuffer (node:internal/streams/writable:389:12) at _write (node:internal/streams/writable:330:10) at Socket.Writable.write (node:internal/streams/writable:334:10) at Framer.ondata (C:\Users\TheEb\Desktop\Code\McSPAM\node_modules\readable-stream\lib_stream_readable.js:681:20) at Framer.emit (node:events:394:28) at addChunk (C:\Users\TheEb\Desktop\Code\McSPAM\node_modules\readable-stream\lib_stream_readable.js:298:12) { errno: -4077, code: 'ECONNRESET', syscall: 'write' }

My best guess is you are on WiFi had some stability issues as you are (possibly) using another computer on the same lan.

Is there a way to catch this error before it makes the bot leave the server?

Also getting this: Is this because of lag? Error: Event blockUpdate:(124, 72, 302) did not fire within timeout of 5000ms

You can't catch this error. It is considered a "fatal error" as the communication between you and the remote server have been disconnected.

You can't catch this error. It is considered a "fatal error" as the communication between you and the remote server have been disconnected.

But I could always wrap it in a trycatch and use this?

function makeBot() {
// the code
}
try {
makeBot()
}
catch(e) {
console.log('disconnected, reconnecting')
makeBot()
}

[kashalls]

It would be easier to use a process manager such as pm2 to restart the script when it exits. This would just make it start again after it errors out and then it would just crash after the second.

You might want to find out first why you're having network issues in the first place.

[JIBSIL]

Thanks for the advice. My network is fine, I can watch netflix on mutliple screens, I run my own minecraft server.. it must be something with my computer or mineflayer

[u9g]

Try restarting your pc

[rom1504]

try checkTimeoutInterval:60*1000 (but default is 30s so if you're lagging that hard nothing will work anyway)

what is your ping with that server ? (do ping <server ip> in the term)
