Why will the raycast not work on the client?

I have it so that both the host and client can spawn cubes on the map by clicking on it at the beginning of the game. I can spawn cubes perfectly on the server but it spawns the cubes at (0,0,0) on the client. Here is the current script.

 [SerializeField] public Transform shootLocation;
 [SerializeField] public GameObject cannonBall;
 [SerializeField] public float shootingSpeed;
 [SerializeField] public static int blocks;
 [SerializeField] public GameObject cube;
 private Vector3 dropLocation;

 void Start () {
     blocks = 5;
 }
 
 void Update () {

     if (Input.GetMouseButtonDown(0))
     {
         if (blocks > 0)
         {
             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             RaycastHit hit;
             if (Physics.Raycast(ray, out hit))
             {
                 if (hit.transform.name != "null" && hit.transform.name != "wall")
                 {
                     dropLocation = new Vector3(hit.point.x, hit.point.y + 1.5f, hit.point.z);
                     CmdSpawn();
                 }
             }
         }
         else
         {
             CmdFire();
         }
     }
 }

 [Command]
 void CmdSpawn()
 {
     blocks = blocks - 1;
     var block = Instantiate(cube, dropLocation, Quaternion.identity);
     NetworkServer.Spawn(block);
 }

 [Command]
 void CmdFire()
 {
     var shell = Instantiate(cannonBall, shootLocation.position, shootLocation.rotation);
     shell.GetComponent<Rigidbody>().velocity = shell.transform.forward * shootingSpeed;
     NetworkServer.Spawn(shell);
 }

}

It seems that when CmdSpawn is called, it is called for the host and not the client. Any help to get it spawned on the client will be greatly appreciated.
