TypeError: Cannot set properties of undefined (setting 'heldItem') at EventEmitter.updateHeldItem (node_modules\mineflayer\lib\plugins\inventory.js:366:25) at EventEmitter.setQuickBarSlot (node_modules\mineflayer\lib\plugins\simple_inventory.js:59:9) at listOnTimeout (node:internal/timers:569:17) at process.processTimers (node:internal/timers:512:7)

Your current code

function daddy() {
  setTimeout(() => {
    const playerHead = bot.inventory.items().find(item => item.name === 'player_head');
    if (playerHead) {
      bot.setQuickBarSlot(4);
      console.log('%cdaddy occurred (4)', 'color: red');
    } else {
      bot.setQuickBarSlot(0);
      console.log('%cdaddy occurred (0)', 'color: red');
    }
    setTimeout(() => {
      bot.activateItem();
    }, 6000);
  }, 12000);
}
setInterval(daddy, 18000);
daddy();
/*
*/

Expected behavior

It is supposed to set quick bar slot to 4 if the bot has a player_head in his inventory, else it will set it to 0

Additional context

usually the code works but its giving that error randomly like every 15-20 minutes

[zefir-git]

It looks like bot.entity is undefined. Is your bot logged into a server?
