cannot read properties of undefined (reading 'position') Minecraft mineflayer

Question

I'm programming a Minecraft bot to follow me, I used this code in lot of projects before 8 months and it worked. But now I have a problem that NodeJS is saying he cannot read 'position'. Code :

const mineflayer = require("mineflayer")
const { pathfinder, goals, Movements } = require('mineflayer-pathfinder')
const GoalFollow = goals.GoalFollow

const bot = mineflayer.createBot({
    host: "localhost",
    port: 57470,
    version: "1.16.5",
    username: "BotWG"
})
bot.loadPlugin(pathfinder)

function followPlayer() {
    bot.chat("I've spawned")
    const playerFilter = entity => entity.type === "player"
    const player = bot.nearestEntity(playerFilter)
    if(!player) return
    const playerTF = bot.players[player]
    const mcData = require("minecraft-data")(bot.version)
    const mcMovements = new Movements(bot, mcData)
    bot.pathfinder.setMovements(mcMovements)

    const goal = new GoalFollow(playerTF, 1)
    bot.pathfinder.setGoal(goal, true)
}

bot.on("spawn", followPlayer)

I've done this code before 8 months ago and it worked. I've installed all the needed packages and when I active the bot he'll join to my world and write "I've joined" then he'll leave and show me this error:
