NullReferenceException: Object reference not set to an instance of an object

For the life of me I cannot understand why I get the error: NullReferenceException: Object reference not set to an instance of an object CreateRandomPoulpi.Start () (at Assets/Scripts/CreateRandomPoulpi.cs:21)

The line its complaining about is: octo.transform.parent = newParent.transform;

 public class CreateRandomPoulpi : MonoBehaviour {
     
     public GameObject enemyPrefab;
     public float numEnemies;
     public float xMin = 19F;
     public float xMax = 85F;
     public float yMin = 3.5F;
     public float yMax = -4.5F;
     
     void Start () {
         
         GameObject newParent = GameObject.Find("1 – Background Elements");
         
         for (int i = 0; i < numEnemies; i++)
         {
             Vector3 newPos = new Vector3(Random.Range(xMin, xMax), Random.Range(yMin, yMax), 0);
             GameObject octo = Instantiate(enemyPrefab, newPos, Quaternion.identity) as GameObject;
             octo.transform.parent = newParent.transform;
         }
         
     }
 }

Any help is much appreciated.
