Need help with Networking spawn error

I have created a script that works for the most part, the bullets are created, client can see them and be affected by them, but I have one problem, every time I shoot it spawns 2 bullets, 1 that goes forward like it is supposed to and one that just floats there. Every time I shoot I get this error

SpawnObject for bullet(Clone) (UnityEngine.GameObject), NetworkServer is not active. Cannot spawn objects without an active server.
UnityEngine.Networking.NetworkServer:Spawn(GameObject)
PistolScript:Rpcshoot() (at Assets/PistolScript.cs:70)
PistolScript:InvokeRpcRpcshoot(NetworkBehaviour, NetworkReader)
UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()


How can I fix this?

 

Looks like you are trying to spawn networked objects from the client. You can only call NetworkServer.Spawn on the server.
