How to fix this log spam when I kill a entity with no item equipped in the mainhand slot

[blissful tusk]

when I kill a mob with no item in my hand, this log starts appearing, I want to get rid of this log, anyone that could help me please answer this question

world.afterEvents.entityDie.subscribe((fx) => {
    const killer = fx.damageSource.damagingEntity
    const killed = fx.deadEntity

    if (killer.typeId === "minecraft:player") {
        const itemEquipped = killer.getComponent("minecraft:equippable").getEquipment('Mainhand')
        if (killed.typeId === "minecraft:player") {
            if (itemEquipped.typeId === "fec:tenacity" || itemEquipped.typeId === "fec:tenacity_axe") {
                killed.runCommand(`particle fec:tenacity_player_kill_fx ~~0.5~`)
                killed.runCommand(`particle fec:tenacity_player_kill_flash ~~0.5~`)
            }
        } else {
            if (itemEquipped.typeId === "fec:tenacity" || itemEquipped.typeId === "fec:tenacity_axe") {
                killed.runCommand(`particle fec:tenacity_entity_kill_fx ~~0.5~`)
                killed.runCommand(`particle fec:tenacity_entity_kill_flash ~~0.5~`)
            }
        }
    } else return 0;
})

this is my code for that thing

just add ? After itemEquipped

[unkempt swift]

or just add a && itemEquipped after your killed.typeId === "minecraft:player" if

[nimble lagoon]

Yeah I was about to say that lmao

Both works tho

[blissful tusk]

wait let me try

[blissful tusk]

idk where I should place the ? thing

[nimble lagoon]

I already said it, after the itemEquipped

So kind alike itemEquipped?.typeId === ''

[blissful tusk]

ok that work

on my first try it failed because I didn't add the ? at the second condition of itemEquipped

that's why i asked twice 😐

sorry

thanks for the solution 🙂
