api bug?

[Smartin-b]

im calling this

    @Override
    public Map<CommonSlotReference, ItemStack> getItems(LivingEntity wearer) {
        Map<CommonSlotReference, ItemStack> map = new HashMap<>();
        EntitySlotLoader.getEntitySlots(wearer).forEach((id, slot) -> {
            SlotReference slotReference = SlotReference.of(wearer, slot.name(), slot.amount());
            ItemStack stack = slotReference.getStack();
            if (stack != null && !stack.isEmpty()) {
                map.put(convert(slotReference), slotReference.getStack());
            }
        });
        return map;
    }

as part of an abstraction including accessories.
the problem on neoforge this resulted in
