Null reference exception from list.

Hi I have a script with a list containing game objects to be added later. I am trying to access this list in another script but it is throwing a null reference exception error. Even checking if list is null throws an error. Please help.

1st script:

public List<GameObject> walkablePathObjects = new List <GameObject>();

2nd script:

[SerializeField] PathfindingToolScript pathfindingToolScript;

if (pathfindingToolScript.walkablePathObjects == null){
            return;
        }

If your if checking is throwing null, you should be debugging.

  1. Find out what is null
  2. Find out why it’s null
  3. Fix it!

So, is pathfindingToolScript null?

It was lol, my apologies. The simplest of things get overlooked.
