    Hello, sorry if my english is bad.
    So I'm currently making an RTS game. There are lots of types of characters so I decided to use scriptable objects to create different types of characters. I also created a base prefab which contains the basic components needed for a character, designed that other components will be added later on instantiation to create the different units. I inserted this base prefab on my NetworkManager as a spawnable prefab.
    I spawn units like this:
    Code (CSharp):
    1. [Command]
    2.     public void CmdSpawnObject (int spawnableObjectIndex, Vector3 position, Quaternion rotation) {
    3.        
    4.         //gets base prefab
    5.         GameObject go = NetworkManager.singleton.spawnPrefabs[UnitSpawnIndex];
    6.        
    7.         //gets desired unit scriptable object
    8.         PlayerUnit playerUnit =  unitGroup.units[spawnableObjectIndex];
    9.        
    10.         //instantiates the base prefab
    11.         go = Instantiate (go, position, rotation);
    12.        
    13.         //adds components to the base prefab using the sciptable object
    14.         playerUnit.Initialize(go);
    15.        
    16.         //assigns the unit to the player
    17.         NetworkIdentity ni = go.GetComponent<NetworkIdentity> ();
    18.         NetworkServer.SpawnWithClientAuthority (go, connectionToClient);
    19.         RpcAssignObject (ni, spawnableObjectIndex);
    20.  
    21.     }
    This creates a problem that only the server has the version of the unit that has the added components. The client on the other hand instantiates only the base prefab.

    Because of this, I tried to also add the needed components using a ClientRpc. This made it so that the unit on the client has the same components. But the when I invoke Commands on the added components this error comes up:

    Thank you to anyone who will help.

    Code (CSharp):
    1. NetworkIdentity ni = go.GetComponent<NetworkIdentity> ();
    you're calling networkidentity component in server but clients don't know that component try this
    Code (CSharp):
    1. RpcAssignObject (go, spawnableObjectIndex);
    and in RpcAssignObject get networkidentity component with go.GetComponent<NetworkIdentity>();
