Missing Component Exception

Hey guys I am getting the following error :

MissingComponentException: There is no 'MeshRenderer' attached to the "Tutorial Transitional ramp" game object, but a script is trying to access it.

However, I do have a MeshRender attached to the gameObject. The script is working as well. However, I still get this error. Script below.

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class turn_off_renderer : MonoBehaviour {

 // Use this for initialization

 public MeshRenderer campmeshrend;
 
 void Start()
 {
     campmeshrend = gameObject.GetComponent<MeshRenderer>();
     campmeshrend.enabled = false;
 }

 // Update is called once per frame
 void Update () {
     
 }

}
