Clients Communicating with a Server Singleton

I am having problems sending Commands from a Client to a Server Singleton

The Player prefab has a NetworkBehavior called NetworkSetup on it which implements OnStartLocalPlayer(). In that function I find the Singleton NetworkProductManager (derived from Network Behavior with NetworkIdentity) in the mission with a GameObject.Find().getComponent().


Then later the client uses a local Canvas (also on the Player prefab) to call NetworkSetup.RequestLoadProduct() which in turn calls NetworkProductManager.CmdLoadProduct() ( a Command).

On the host the function is called but on remote clients I get this error

Below is the relivant code snippet. Can someone point out what I am missing or doing wrong?

Code (csharp):

1.  
2.  
3. public class NetworkSetup : NetworkBehaviour {
4.  
5. [SerializeField] NetworkProdcutManager netProdMan = null;
6.  
7. public override voidOnStartLocalPlayer ()
8. {
9. netProdMan = GameObject.Find ("ProductManager").GetComponent<NetworkProdcutManager>();
10. if (netProdMan == null)
11. {
12.   Debug.Log ("did not find netProdMan");
13. }
14. base.OnStartLocalPlayer ();
15. }
16.  
17. public void RequestLoadProduct()
18. {
19. if (netProdMan == null)
20. {
21. Debug.Log ("RequestLoadProduct:: Error no Network Product Manager");
22. return;
23. }
24. if (!isLocalPlayer)
25. {
26. Debug.Log("RequestLoadProduct:: Only call for Our Client");
27. return;
28. }
29. Debug.Log ("Local RequestLoadProduct");
30. netProdMan.CmdLoadProduct ();
31. }
32.  
33. }
34.  

Code (csharp):

1.  
2. [RequireComponent (typeof(NetworkIdentity))]
3. publicclass NetworkProdcutManager : NetworkBehaviour
4. {
5. [Command]
6. publicvoidCmdLoadProduct()
7. {
8. Debug.Log ("NetworkProdcutManager::LoadProduct isServer: "+ isServer + " isLocalPlayer: " + isLocalPlayer);
9. }
10. }
11.  

Code (csharp):

1.  
2. public class DebugCanvas : MonoBehaviour {
3.  
4. private NetworkSetup nSetUp = null;
5.  
6. voidStart()
7. {
8. nSetUp = GetComponent<NetworkSetup> ();
9.  
10. }
11. //Client Only
12. public void onLoadProductButtonPressed()
13. {
14. Debug.Log ("onLoadProductButtonPressed");
15. nSetUp.RequestLoadProduct ();
16. }
17. }
18.  
19.  

 

So I figured it out

Code (csharp):

1.  
2. public class NetworkSetup : NetworkBehaviour {
3. //Client
4. public void RequestLoadProduct()
5.  {
6.  
7. if (netProdMan == null)
8.  {
9.   Debug.Log ("RequestLoadProduct:: Error no Network Product Manager");
10.   return;
11.  }
12. if (!isLocalPlayer)
13.  {
14.   Debug.Log("RequestLoadProduct:: Only call for Our Client");
15.   return;
16.  }
17.  
18. Debug.Log ("NetworkSetup::RequestLoadProduct isServer:" + isServer );
19.  
20.  
21.  
22.   CmdLoadProduct ("Monkey Nutz");
23.  }
24.  
25.  [Command]
26. public void CmdLoadProduct (string data)
27.  {
28. Debug.Log ("NetworkSetup::CmdLoadProduct isServer:" + isServer);
29. if (netProdMan == null)
30.  {
31.   Debug.Log ("CmdLoadProduct::Server needs Network Product Manager");
32.  
33.   netProdMan = GameObject.Find ("ProductManager").GetComponent<NetworkProdcutManager>();
34.  }
35.  
36. netProdMan.LoadProduct (data);
37.  }
38. }
39.  

Code (csharp):

1.  
2. [RequireComponent (typeof(NetworkIdentity))]
3. public class NetworkProdcutManager : NetworkBehaviour
4. {
5.  
6. //Executed on Server
7. public void Load Product(string data)
8.  {
9. if (!isServer)
10.   return;
11. //Loadthingsandwhatnot
12. Debug.Log ("NetworkProdcutManager::CmdLoadProduct load: "+ data );
13.  
14. RpcLoadProduct (data);
15.  
16.  }
17. //Executed on Client
18.  [ClientRpc]
19. voidRpcLoadProduct(string data)
20.  {
21.     Debug.Log ("NetworkProdcutManager::RpcLoadProduct load: "+ data);
22.  }
23. }
24.
