Your current code

// Here I tell node.js mineflayer and a few other plugins are required to load
const mineflayer = require('mineflayer')
const mineflayerViewer = require('prismarine-viewer').mineflayer
const pathfinder = require('mineflayer-pathfinder').pathfinder
const pvp = require('mineflayer-pvp').plugin
const Movements = require('mineflayer-pathfinder').Movements
const goals = require('mineflayer-pathfinder').goals
const navigatePlugin = require('mineflayer-navigate').plugin

// Here, we set up the server connection (in this case, my skin plugin server)
const bot = mineflayer.createBot({
    host: 'SonicJavaBots.aternos.me',
    port: '37867',
    username: "SonicandTailsCDb",
    version: '1.18.2'
})

// Here the variables need to be set. It's important to load them first, otherwise there will be an error.
let attackCurrent = false
let guardPos = null

// Here, we reset the guard position.
bot.on('spawn', () => {
  stopGuarding()
  bot.chat('The guard position was reset. Sorry!')
})
// Now here comes the fun part: the coding. This is the AI, basically.
bot.loadPlugin(pathfinder)
bot.loadPlugin(pvp)
bot.loadPlugin(navigatePlugin)

// Assign the given location to be guarded
function guardArea (pos) {
  guardPos = pos
  let attackCurrent = false
  // We we are not currently in combat, move to the guard pos

    moveToGuardPos()
  }
}

// Cancel all pathfinder and combat

  guardPos = null
  bot.pvp.stop()
  bot.pathfinder.setGoal(null)
}

// Pathfinder to the guard position

  if (!guardPos) return
  bot.pathfinder.setMovements(new Movements(bot))
  bot.pathfinder.setGoal(new goals.GoalBlock(guardPos.x, guardPos.y, guardPos.z))
}

// Called when the bot has killed it's target.
bot.on('stoppedAttacking', () => {
  if (guardPos) {
    moveToGuardPos()
  }
})

function lookAtNearestPlayer () {
  const playerFilter = (entity) => entity.type === 'player'

  if (!playerEntity) return
  
  const pos = playerEntity.position.offset(0, playerEntity.height, 0)
  bot.lookAt(pos)
}

  if (!guardPos) return // Do nothing if bot is not guarding anything

  // Only look for mobs within 16 blocks
  const filter = e => e.type === 'mob' && e.position.distanceTo(bot.entity.position) < 16 &&
                    e.mobType !== 'Armor Stand' && e.mobType !== 'Creeper'

  const entity = bot.nearestEntity(filter)
  if (entity) {
    // Start attacking
    bot.pvp.attack(entity)
  } else if (!bot.pvp.target) {
    // Move towards the nearest player if the bot is not attacking anything
    const playerFilter = (entity) => entity.type === 'player'
    const playerEntity = bot.nearestEntity(playerFilter)

    if (!playerEntity) return

    const pos = playerEntity.position
    bot.navigate.to(pos)
  }
}

bot.on('physicsTick', onPhysicsTick)

// Listen for player commands
bot.on('chat', (username, message) => {
  // Guard the location the player is standing
  if (message === 'guard') {
    const player = bot.players[username]
    let attackCurrent = false
    if (!player) {
      bot.chat("I can't see you.")
      return
    }

    bot.chat('I will guard that location.')
    guardArea(player.entity.position.offset(0, 0, -1))
  }

  // Stop guarding
  if (message === 'stop') {
    bot.chat('I will no longer guard this area.')
    stopGuarding()
    let attackCurrent = null
  }
})

Expected behavior

A clear and concise description of what you expected to happen.
The bot would join, as soon as I say "guard", the bot follows me.

The error was:

Also, the function onPhysicsTick was written by ChatGPT.
That's all.

[SonicandTailsCD]

Also, please don't close this. I've never closed one, so I want to try out closing it.

[amoraschi]

mineflayer-navigate is deprecated iirc. Use mineflayer-pathfinder instead.

[SonicandTailsCD]

Btw what's "iirc"?

[SonicandTailsCD]

Ok! How do I do that?

[amoraschi]

Instead of taking code from sources like ChatGPT, try learning the basics of JS and understand each part of your code.

Sorry, but I don't think there's a better way than this.

[SonicandTailsCD]

I know the basics of JS.

[SonicandTailsCD]

But sometimes I need quick answers. Besides, the rest of the code, that was made by me! I only asked ChatGPT to write a function.

[amoraschi]

Sorry, the code is from examples/guard.js with some additional code, and I assumed you didn't know the basics because I read:

Did you try any method from the API? No, I don't know how.
Did you try any example? yes
Any error from those? yes

If you want to get started with mineflayer-pathfinder, this might be a good video (I haven't checked if the code still works tho):

[SonicandTailsCD]

I'm sorry if I insulted/have been mean to you. :(

[SonicandTailsCD]

Okay! I'll try. But one thing: maybe you can help correct my code?

[SonicandTailsCD]

No problem, lah. I forgive you :)

[SonicandTailsCD]

This doesn't help tho.

[SonicandTailsCD]

Alright. I need to correct this deprecation error...

[SonicandTailsCD]

Can you help? I don't have much time.

[amoraschi]

Well, you need to provide more info, your error on this issue is an assertion error, not a deprecation error/notice, and you didn't provide the new code you're using

[SonicandTailsCD]

Oh.

[SonicandTailsCD]

Well, how do I change the code to match mineflayer-pathfinder? Also I didn't change my code. I can't get it to load.

[rom1504]

Ask chatgpt to fix it

[SonicandTailsCD]

LOL good joke. ChatGPT doesn't know 'bout mineflayer-pathfinder.

[SonicandTailsCD]

(No offense - I don't know if that was offensive or not, if it is, I'm very sorry.)

[SonicandTailsCD]

…

[SonicandTailsCD]

Seems like no one's responding. Oh well. I'll close it soon.

[1ProCrafters]

Check that each of the required plugins is installed and up-to-date. If that does not resolve the issue, you may need to review the plugin code to ensure that it is valid and compatible with the version of mineflayer being used.

[SonicandTailsCD]

This doesn't help.

[SonicandTailsCD]

As of now, no responses yet... I'm closing this in 7 days if not solved :(

[rom1504]

Recommend you use mineflayer-pathfinder

How do I do that? The API is confusing

[SonicandTailsCD]

I completed that, that was hard! :)
