"Accessed none CallFunc_Array_Get_Item" without using array

Hi, I’m confronted some difficulty.
This error occur suddenly.

Actually, I change something, but not this blueprints.

Here is two blueprints related to this error logs.

As you can see it, I dont’t use and access array in GameMap.

I dont’t know why this error occur.

This is what i checked.

  1. When I don’t use SpawnPawn in GameMap, error doesn’t occur.
  2. When I use SpawnPawn in GameMap, error occur even I set it doesn’t work anything.
  3. I checked all arrays and values in SpawnPawn whis is implemented in GameMap. And nothing wrong on that.

What is the problem in my function?
