Server crash when pulling items with itemduct.

[Powerxd]

Hello!

I have a problem with my mod.

As you can see by the title, when i try to remove items from my tileentity with itemducts or ae2 server crashes.

I have multiple tile entities, but this happens only with one.

I have no idea whats causing this. Any suggesions?

Heres the crash log https://pastebin.com/89B1WJSS

Thanks!

There is a java.lang.NullPointerException thrown by cofh.thermaldynamics.duct.attachments.servo.ServoItem.handleItemSending. Somewhere here in your code must be an element that is either null where it shouldn't be, or something caused it to not load/initialize properly.

Yeah. I know that much, but i cant find the null,  thought maybe someone has expirienced this issue. Since it started happening once i updated forge, and thermal expansion stuff.

Okay i found the issue. I guess forge now doesnt like when you return null instead of ItemStack.EMPTY();

@Override
    public ItemStack extractItem(int slot, int amount, boolean simulate)
    {
		return ItemStack.EMPTY;
		//return null;
    }

Itemstacks are supposed to NEVER be null

I mean i knew it, but i guees i forgot it. This is the only place in my code where it returns null. Other places it returns ItemStack.EMPTY();

I guess ill be more careful
