Describe the Bug

Extract an item from a moving contraption assembled by shift-clicking, and disassemble the contraption. It crashes (or logs an error) with the message java.lang.IllegalArgumentException: Transfer variant may not be blank..

Reproduction Steps

1. Construct any moving contraption with an attached chest containing some items (maybe reproducible with other storage blocks e.g. barrel) - I had reproduced w/ windmill (not crashes, but could lead to dupe bug in Singleplayer), minecart (crashes, see the comment from #1211 (comment) for vids), gantry (crashes)
2. Remove item from the inventory by shift-clicking
3. Disassemble the contraption

Expected Result

It should be disassembled properly

Possible Solutions

• I have locally fixed the issue by copying the return value (L102) of StorageInteractionContainer.getItem in my dev env. It seems that the shift-click interaction modifies the return value of getItem directly. But I have no idea if the solution could produce other side effects.
  

  Create/src/main/java/com/simibubi/create/content/contraptions/MountedStorageInteraction.java

  Lines 96 to 103 in 49cc17e

  	@Override
  	public ItemStack getItem(int slot) {
  	if (oob(slot))
  	return ItemStack.EMPTY;
  	ItemStackHandler handler = handlerForSlot(slot);
  	slot = actualSlot(slot);
  	return handler.getStackInSlot(slot);
  	}

• Another possible solution is changing the Porting-Lib code. Apply the isEmpty filter whenever ItemStackHandler.nonEmptyViews is called.
  https://github.com/Fabricators-of-Create/Porting-Lib/blob/41c9aacb30f43e0993c63f1da4438e1943fc6697/transfer/src/main/java/io/github/fabricators_of_create/porting_lib/transfer/item/ItemStackHandler.java#L101-L111

I've had this one too, with gantries.
It seems removing a stack (through shift clicking or not) of a moving contraption causes it.
