Third Party Unity Mirror Class with Interface

Hello all,
I was wondering if anyone has tried to do something like this before with Mirror. If not should there be another way I go about it. The jist is I have my player looking at some sort of item on screen. It is detected through a raycast. The item inherits from an Interactable interface. The error I am getting from Mirror (Weaver) is attached below.
I think I may need a custom serializer if I want to do it this way, but maybe I should just avoid this approach in general? Would just be nice to be able to use an interface for all the interactable items.

PlayerItemDetection

Code (CSharp):

1.  
2.    void LookForInteractable()
3.     {
4.         // if we hit an interactable item
5.        if (Physics.Raycast(this.transform.position + _rayCastOffset, transform.forward, out _hit, 4f, InteractLayer))
6.         {
7.             if (_controls.Player.Interact.ReadValue<float>() != 1) return;
8.  
9.             var interactable = _hit.collider.gameObject.GetComponent<IInteractable>();
10.             if (interactable != null && interactable.CanInteract())
11.             {
12.                 CmdInteract(interactable);
13.             }
14.         }
15.     }
16.  
17.     [Command]
18.     void CmdInteract(IInteractbale i)
19.     {
20.         i.Interact();
21.     }
22.  

Example Item

Code (CSharp):

1.  
2. public class ItemController : NetworkBehaviour, IInteractable
3. {
4.      public void Interact(){
5.           // Do something with the item
6.      }
7. }
8.  
9. public interface IInteractable {
10.      void Interact();
11. }
12.
