TypeError: Cannot read properties of null (reading 'version')

idk what just happened, im just adding a configuration.json feature. anyways here's my code without the config.json

const mineflayer = require('mineflayer');
const { pathfinder, Movements, goals: { GoalNear } } = require('mineflayer-pathfinder');
var Vec3 = require('vec3').Vec3;
const jsonfile = require('jsonfile')

const bot = mineflayer.createBot({
    "host": "ruby.magmanode.com",
    "username": "boty",
    "auth": "offline",
    "port": 31963,
    "version": "1.20.4"
})
bot.loadPlugin(pathfinder)

function walk2goal(x,y,z, range) {
    const mcdata = require("minecraft-data")(bot.version);
    const mvs = new Movements(bot, mcdata);
    mvs.allow1by1towers = false // Do not build 1x1 towers when going up
    //mvs.canDig = false // Disable breaking of blocks when pathing 
    bot.pathfinder.setMovements(mvs);
    bot.lookAt(new Vec3(x, y, z))
    bot.pathfinder.setGoal(new GoalNear(x, y, z, range), false);
}

function between(min, max) {  
  return Math.floor(
    Math.random() * (max - min) + min
  )
}

bot.on("login", () => {
    console.log("Logged in!");

    bot.on("spawn", () => {
        console.log(`Spawned in ${bot.game.gameMode}.`);
    })
})

var whileWalk = false;
var isReached = true; // Because initially our destination is reached
var rwalkPos = new Vec3(0,0,0); // 0,0,0 pos. its because the bot digs everything to enter destination

bot.on("physicsTick", () => {
    if (whileWalk && isReached) {
        isReached = false; // because our destination will be different
        var offsX = between(-3,3);
        var offsZ = between(-3,3);
        console.log(new Vec3(rwalkPos.x+offsX, rwalkPos.y, rwalkPos.z+offsZ))
        walk2goal(rwalkPos.x+offsX, rwalkPos.y, rwalkPos.z+offsZ, 0);
    }
})

bot.on("goal_reached", (goal) => {
    console.log(`pathfinding to [${goal.x}, ${goal.y}, ${goal.z}] is done!!`);
    isReached = true;
    if (whileWalk){
        bot.waitForTicks(100)
    }
})

bot.on("path_stop", () => {
    isReached = true;
    console.log("Stopped!")
})

bot.on('whisper', (username, message) => {
    if (username === bot.username) return;
    if (username === botOwner) {
        if (message === "walk2me") {
            const ownerEntity = bot.players[botOwner]?.entity;
            const { x: posX, y: posY, z: posZ } = ownerEntity.position;
            walk2goal(posX, posY, posZ, 2);
        } else if (message === "walkRandomly") {
            if (whileWalk && !isReached) {whileWalk=false; isReached = true};
            var myself = bot.entity;
            rwalkPos = myself.position; // starting pos
            whileWalk = true;
        } else if (message === "stop") {
            bot.pathfinder.stop();
            if (whileWalk && !isReached) {
                whileWalk = false;
                isReached = true;
                walk2goal(rwalkPos.x, rwalkPos.y, rwalkPos.z, 0);
            };
        }
    }
})

bot.on("message", (jsonMsg, position, sender, verified) => {
    let msg = jsonMsg.toString()
    console.log(`[${position}] ${msg}`)
})

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

the error:

Just setting the version to false is emoughe lmao >.<

[bulieme]

nvm what is this

[wgaylord]

Remove the " from around the names of the arguments on the createBot.

See the example in the readme of the repo.

same problem, it seems that it happened when updating to the latest version of mineflayer UPDATE: The problem is older version (For some reason it installs everything and I download the version that was the problem, update to the most recent one and this problem will be fixed (problem with 4.0.0))

[extremeheat]

I believe this was fixed recently in a PR, so you can update with npm update
