How to use isTrigger to spawn enemy with enemyAI script

I don't know If It's ok to post the whole script here because It's quite long. My problem is that I have a functional EnemyAI script. However, when I want to spawn an enemy using trigger, the game crash.

I followed the EnemyAI script from Youtube user here : https://www.youtube.com/watch?v=U1nPbJZ1hlc

And I followed th SpawnTrigger from Youtube user here : https://www.youtube.com/watch?v=xHjwGJIbW60

The error message is this ::

NullReferenceException: Object reference not set to an instance of an object GhostAI.SearchForPlayer () (at Assets/Scripts/GhostAI.cs:72) GhostAI.Update () (at Assets/Scripts/GhostAI.cs:63)

The error in code is this :: if (Vector3.Angle(Vector3.forward, transform.InverseTransformPoint(fpsc.transform.position)) < 60f)

Any suggestion would be appreciated
