Accessed None trying to read property CallFunc_Array_Get_Item

I have a save game system when my game is paused. So you click Escape then Save and you are supposed to save your game. It should work because I saw the tutorial on YouTube but the difference here is that I save in Paused state. I tried repairing it by unPausing the game before the save but it didn’t work. Here are some screenshots if you could help. Thanks!

One of the arrays is empty at the time of the call. After each array is received, check for the length of the array, and if it is 0, print the message. Thus, you can understand which of the arrays is empty and try decide why it is empty.

How can I discover which of the arrays is empty? Sorry for asking but I’m kind of new.
