Can't dispose NativeArray

I get the following error on executing:
"InvalidOperationException: The NativeArray can not be Disposed because it was not allocated with a valid allocator."

Code (CSharp):

1.  
2. protected override JobHandle OnUpdate(JobHandle inputDeps) {
3.             _ProducerHandle.Complete();
4.             _ProducerHandle = default;
5.  
6.             if (UnityEngine.Input.GetKeyDown(UnityEngine.KeyCode.S)) {
7.                 _SpawnerRegistry.RegisterEntity(new NetworkIdentity());
8.             }
9.  
10.             var networPrefabEntity = _NetworkPrefabQuery.GetSingletonEntity();
11.             var networkEntityPrefabs = GetBufferFromEntity<NetworkEntityPrefabs>(true)[networPrefabEntity];
12.  
13.             using (var networkIdTypes = _SpawnerRegistry.GetNetworkIdentityTypes(Allocator.Temp)) {
14.                 for (int i = 0; i < networkIdTypes.Length; i++) {
15.                     using (var networkIdentities = _SpawnerRegistry.GetNetworkIdentitiesOfType(networkIdTypes[i], Allocator.Temp))
16.                     using (var entities = new NativeArray<Entity>(networkIdentities.Length, Allocator.Temp)) {
17.  
18.                         EntityManager.Instantiate(networkEntityPrefabs[networkIdTypes[i]].Prefab, entities);
19.                         var networkIdFromEntity = GetComponentDataFromEntity<NetworkIdentity>();
20.                         for (int j = 0; j < entities.Length; j++) {
21.                             networkIdFromEntity[entities[j]] = networkIdentities[j];
22.                         }
23.                     } // Error happens here
24.                 }
25.                 _SpawnerRegistry.Clear();
26.             }
27.  
28.             return inputDeps;
29.         }  
30.

Ahh sometimes...

For anyone with an similar problem...

_SpawnerRegistry.GetNetworkIdentitiesOfType(networkIdTypes, Allocator.Temp)
returns a NativeArray from a NativeList...

So the NativeArray can't be disposed. I have to return the original NativeList to dispose it.

Code (CSharp):

1. // I create a NativeList but I do return a NativeArray.
2. //This isn't possible because you can't dispose it.
3. internal NativeArray<NetworkIdentity> GetNetworkIdentitiesOfType(int type, Allocator allocator) {
4.     var networkIdentities = new NativeList<NetworkIdentity>(allocator);
5.     if (_Spawner.TryGetFirstValue(type, out NetworkIdentity item, out NativeMultiHashMapIterator<int> it)) {
6.         do {
7.             networkIdentities.Add(item);
8.         } while (_Spawner.TryGetNextValue(out item, ref it));
9.     }
10.     return networkIdentities;
11. }

Anyway I think the feature to dispose an NativeArray from an NativeList would be nice to have..
Usecase :

• Disposing NativeArray from NativeLists in Jobs
• Hide the ability to add/remove items to a collection and and dispose of them after usage.
