SpawnObject for ak(Clone) (UnityEngine.GameObject), NetworkServer is not active. Cannot spawn objects without an active server - unity3d

Question

helloI'm making an object in Unity that gives players random weapons when they hover over it, but it always gives me this warning and doesn't create it.
[ClientRpc]
public void spawnTime()
{
StartCoroutine(spawn());
}
public IEnumerator spawn()
{
Debug.Log("oldu");
yield return new WaitForSeconds(1);
int a = Random.Range(0, guns.Length);
GameObject gun =Instantiate(guns[a], spawnPoint.position,Quaternion.identity);
gun.transform.SetParent(transform);
NetworkServer.Spawn(gun);
}

Answer 1

This is because of you are calling the spawn function from client. You should call it in server.
[Server]
public void spawnTime()
{
StartCoroutine(spawn());
}
[Server]
public IEnumerator spawn()
{
Debug.Log("oldu");
yield return new WaitForSeconds(1);
int a = Random.Range(0, guns.Length);
GameObject gun =Instantiate(guns[a],
spawnPoint.position,Quaternion.identity);
gun.transform.SetParent(transform);
NetworkServer.Spawn(gun);
uint gunNetId = gun.GetComponent<NetworkIdentity>().netId;
uint parentNetId = transform.root.GetComponent<NetworkIdentity>().netId;
RpcSetParent(parentNetId, gunNetId);
}
[ClientRpc]
void RpcSetParent(uint parentNetId, uint childNetId)
{
Transform child = NetworkClient.spawned[childNetId].transform;
Transform parent = NetworkClient.spawned[parentNetId].transform;
child.SetParent(parent);
}
Be sure that you are calling the spawnTime() function from something running in server and networked object. You can filter it something like:
Start(){
NetworkIdentity nid = transform.root.GetComponent<NetworkIdentity>();
if(nid.isServer)
{
spawnTime();
}
}
