Bug Unable to see missing scripts via GUI on certain Prefabs Models

Hi! I am using an old scene from 2017. It had a couple of old, unsupported light features here and there but I managed to make it work. Now, upon attempting to make a Prefab from a Prefab Model (by dragging it into a folder), I get the following error:

Code (CSharp):

1. You are trying to replace or create a Prefab from the instance 'rock_small' that references a missing script. This is not allowed.
2. Please change the script or remove it from the GameObject.
3. UnityEditorInternal.InternalEditorUtility:ProjectWindowDrag(HierarchyProperty, Boolean)
4. UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

This suggests that there is at least a missing script in the Prefab Model. Further, I confirmed that around 40% of all the Prefab Models in the scene have at least a missing script using this code:

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. using System.Collections.Generic;
4. using UnityEngine.SceneManagement;
5.  
6. public class SelectGameObjectsWithMissingScripts : Editor
7. {
8.     [MenuItem("Tools/WPAG Utilities/Select GameObjects With Missing Scripts")]
9.     static void SelectGameObjects()
10.     {
11.         //Get the current scene and all top-level GameObjects in the scene hierarchy
12.         Scene currentScene = SceneManager.GetActiveScene();
13.         GameObject[] rootObjects = FindObjectsOfType<GameObject>();
14.  
15.         List<Object> objectsWithDeadLinks = new List<Object>();
16.         foreach (GameObject g in rootObjects)
17.         {
18.             //Get all components on the GameObject, then loop through them
19.             Component[] components = g.GetComponents<Component>();
20.             for (int i = 0; i < components.Length; i++)
21.             {
22.                 Component currentComponent = components[i];
23.  
24.                 //If the component is null, that means it's a missing script!
25.                 if (currentComponent == null)
26.                 {
27.                     //Add the sinner to our naughty-list
28.                     objectsWithDeadLinks.Add(g);
29.                     Selection.activeGameObject = g;
30.                     Debug.Log(g + " has a missing script!");
31.                     break;
32.                 }
33.             }
34.         }
35.         if (objectsWithDeadLinks.Count > 0)
36.         {
37.             //Set the selection in the editor
38.             Selection.objects = objectsWithDeadLinks.ToArray();
39.         }
40.         else
41.         {
42.             Debug.Log("No GameObjects in '" + currentScene.name + "' have missing scripts! Yay!");
43.         }
44.     }
45. }

Provided that I cannot see the missing scripts, how do I delete them?

 

Update 1:
Using

Code (CSharp):

1. DestroyImmediate(currentComponent);

on every missing component didn't work

 

Bump

 

Bump

 

it will nor work as the component is null

 

Nice necro of a 2+-year old post.

Here's what you should do, if anyone comes across this from Google:

UnityEditor.GameObjectUtility.RemoveMonoBehavioursWithMissingScript(gameObject);
