Network Manager NetworkServer.Spawn isn't working

Hey!
I'm making a MP FPS game. And my bullets are projectiles. I can't spawn them in on ther server side I get the NullRefernceException error.

 using UnityEngine;
 using UnityEngine.Networking;
 
 public class PlayerShoot : NetworkBehaviour {
     [SerializeField]
     private Camera cam;
 
     [SerializeField]
     GameObject bullet;
 
     [SerializeField]
     Transform spawn;
 
 
 
     [SerializeField]
     private LayerMask mask;
     // Use this for initialization
     void Start () {
 
     }
     
     // Update is called once per frame
     void Update () {
         if (Input.GetButtonDown("Fire1"))
         {
             Shoot();
         }
     }
 
     void Shoot()
     {
         RaycastHit hit;
         if (Physics.Raycast(cam.transform.position, cam.transform.forward, out hit, float.PositiveInfinity, mask))
         {
             Debug.Log(hit.point);
             GameObject bulletClone = Instantiate(bullet, spawn.position, spawn.rotation);
             bulletClone.transform.LookAt(hit.point);
             bulletClone.transform.Rotate(new Vector3(90, 0, 0));
             CmdFire(bulletClone);
         }
     }
 
     [Command]
     void CmdFire(GameObject bulletSpawn)
     {
         NetworkServer.Spawn(bulletSpawn);
     }
 
 }
