Resolved Can't figure out the cause of the input system error.

I use machine translation, so please forgive me if my English may be unnatural.　
I have written this code for a new object controller tool. It is a tool to test the input system.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEditor;
4. using UnityEditor.Experimental.EditorVR;
5. using UnityEngine;
6. using UnityEngine.XR;
7. using UnityEngine.InputNew;
8.  
9.  
10. public class LaserbeamController : MonoBehaviour, ITool, IUsesRaycastResults, IUsesViewerScale, ICustomActionMap, IProcessInput,
11.     IGetVRPlayerObjects, ISelectObject, IUsesRayOrigin
12. {
13.  
14.     GameObject ManipuratorBase;
15.  
16.     bool ControlObject = false;
17.    
18.     LaserbeamAction laserConInput;
19.  
20.     Vector3 LaserOriginePosition;
21.     private Vector3 offset = new Vector3(0.0f, -0.3f, 0.5f);
22.  
23.    
24.    
25.     GameObject player;
26.  
27. #pragma warning disable 649
28.  
29.     [SerializeField]
30.     GameObject laserPrefab;
31.  
32.     [SerializeField]
33.     GameObject depthController;
34.  
35.     [SerializeField]
36.     ActionMap laserConAction;
37.  
38. #pragma warning restore 649
39.  
40.     public Transform rayOrigin { get; set; }
41.     public ActionMap actionMap { get{ return laserConAction;} }
42.     public bool ignoreActionMapInputLocking { get {return false;} }
43.  
44.  
45.     public void ProcessInput(ActionMapInput input, ConsumeControlDelegate consumeControl)
46.     {
47.         laserConInput = (LaserbeamAction)input;
48.  
49.                    
50.         if(laserConInput.select.wasJustPressed)
51.         {
52.             consumeControl(laserConInput.select);
53.            
54.             if(PrefabUtility.GetCorrespondingObjectFromSource(this.GetFirstGameObject(rayOrigin)).name != "Lightparent")
55.                 {
56.                     Selection.activeGameObject = null;
57.                     Debug.Log("This is not selectable object.");
58.                     return;
59.                 }
60.  
61.             ControlObject = true;
62.             Debug.Log("This is Light Object.");
63.         }
64.        
65.         if(ControlObject == true && laserConInput.apply.wasJustPressed)
66.         Debug.Log("Select Object was released.");
67.            
68.     }

But it doesn't work with the error below.

I have an Action Map file for the code, but is there anything else I am missing?

 

What I needed to do was simply remove the unnecessary variable declarations and use var for the new variables.

 

The ActionMapInput I declared in line 18 of the code caused that error; I used it in line 47, so I added var to it.
