Prefab table can't add Network objects
Hello.
I'm just starting with the fusion tutorials. On the secon one (set Up a scene) when i create a NetworkObject, that one isnt included on the NetworkProjectConfig.PrefabTable, even when it have the isSpawnable check (also don't include the prototipes that brings the fusion unityPackaje). When I rebuild prefab Table it give the following error for all NetworkObjects:
Unable to create prefab asset for Assets/6.SCENES/01_Tests/NetworkTest/NetworkPlayerPrefab.prefab: System.NullReferenceException: Object reference not set to an instance of an object

Any guess why it happens and how solve it?
