Object reference not set to an instance of an object

I follow this tutorial to make the Maze.

I've already finished the "Placing Doors"part, but I have an error during runtime, all I get in the error is NullReferenceException: Object reference not set to an instance of an object, and there is the part of code:

 using UnityEngine;
 using System.Collections;
 
 public class MazeWall : MazeCellEdge {
 
     public Transform wall;
     
     public override void Initialize(MazeCell cell, MazeCell otherCell, MazeDirection direction){
         base.Initialize (cell, otherCell, direction);
         wall.GetComponent<Renderer> ().material = cell.room.settings.wallMaterial;
     }    
 }
