NullReferenceException error in one script and not the other

Questions & Answers
1

I have the following lines of code in two different C# scripts. In one of them it works flawlessly in the other one I get a “NullReferenceException” error:

    private GameObject goh1;
 private GameObject goh2;
 private GameObject goh3;
 private GameObject goh4; 
 private GameObject goh5;
 private GameObject goh6;
 private PlayerCharacter pcClass1;
 private PlayerCharacter pcClass2;
 private PlayerCharacter pcClass3;
 private PlayerCharacter pcClass4;
 private PlayerCharacter pcClass5;
 private PlayerCharacter pcClass6;



// Use this for initialization
 void Start () {
 goh1 = GameObject.Find("PC1");
 goh2 = GameObject.Find("PC2");
 goh3 = GameObject.Find("PC3");
 goh4 = GameObject.Find("PC4");
 goh5 = GameObject.Find("PC5");
 goh6 = GameObject.Find("PC6");
 pcClass1 = goh1.GetComponent();
 pcClass2 = goh2.GetComponent();
 pcClass3 = goh3.GetComponent();
 pcClass4 = goh4.GetComponent();
 pcClass5 = goh5.GetComponent();
 pcClass6 = goh6.GetComponent();
//some stuff that is different between the two files
}

Error message:

NullReferenceException
UnityEngine.GameObject.GetComponent[PlayerCharacter] () (at C:/BuildAgent/work/842f9557127e852/Runtime/ExportGenerated/Editor/UnityEngineGameObject.cs:18)
Targetting.Start () (at Assets/Scripts/CharacterMechanic/Targetting.cs:43)

Any idea on how to get rid of that error? How is that even possible?

Found the problem: the second script was just attached to the gamemaster object while the first script was part of a prefab. Now both are attached to prefabs and no NullReferenceException anymore.
