Mirror plugin in unity ,problems with server and client authority

Question

I'm using mirror.And my player interact with an interactable object, then create a gun for the player and set a property in player's scripts.But i get warning saying that

 Command System.Void M4_Interact::Interact(UnityEngine.GameObject) called on M4_Interact without authority.

The first image tells that i use raycast to check interact,and assign authority,then into the second image's function

enter image description hereenter image description here

If i use functions or other things wrongly or any other mistake.
