Why getting null exception? Trying to get the List<GameObject> from one script to another script ?

Scripting
1

In the first script top:

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

Then in the Start function:

void Start()
    {
        Clone();
        GetComponent<WayPoints>().cloneList = cloneList;
}

In the clone function i add objects to the cloneList.
Using a breakpoint i see tha the cloneList is filled with 10 objects.
Now i want to use this List in another script.

In the other script where i want to use the cloneList i did:

public List<GameObject> cloneList = new List<GameObject>();
public List<GameObject> waypoints;

Then in the Start function

void Start()
    {
        waypoints = this.cloneList;
    }

But i’m getting null exception in the first script on the line:

GetComponent<WayPoints>().cloneList = cloneList;

The cloneList on the right after the = is not null. It’s on the left side something is null.

What i want is to fill the waypoints List in the other script with the cloneList.

Solution in first script just to make one variable the list public

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

In second script

CloneObjects cloneObjectsInstance = FindObjectOfType<CloneObjects>();
waypoints = cloneObjectsInstance.cloneList;

Working.
