What did you try yet?

Did you try any method from the API? Did you try any example? Any error from those?

Your current code

Expected behavior

break the block

Additional context

the invalid item was the hand. The bot didn't had anything in its inventory

[amoraschi]

That's probably caused by bot.equip, what's your code, maybe you're passing a null object to bot.equip

[amoraschi]

That really is understandable, thanks. Maybe it's this

await _this.bot.equip(item, destination);
