NullReferenceException in NetworkConnectionManager.cs when PlayerPrefab is not assigned

[Ceeeeed]

In NGO version 2.11.1, a NullReferenceException is thrown in NetworkConnectionManager.cs at line 975 when PlayerPrefab is not assigned in the inspector.

Current code:

var idHashToSpawn = playerPrefabHash ?? NetworkManager.NetworkConfig.PlayerPrefab?.GetComponent<NetworkObject>()?.GlobalObjectIdHash;

Changing the code to the following fixes the issue:

var idHashToSpawn = playerPrefabHash;

var playerPrefab = NetworkManager.NetworkConfig.PlayerPrefab;
if (idHashToSpawn == null && playerPrefab != null && playerPrefab.TryGetComponent<NetworkObject>(out var playerNetworkObject))
 idHashToSpawn = playerNetworkObject.GlobalObjectIdHash;

After this change, everything works correctly even when PlayerPrefab is not assigned.

The exception occurs after calling:

NetworkManager.StartHost();

while using SinglePlayerTransport.

Environment:

• NGO version: 2.11.1
• Transport: SinglePlayerTransport
• Unity version: 6000.3.11.f1

This just bit me on Unity 6000.4.0f1.

Downgrading to 2.11.0 resolves the problem, so the regression is immediate.

This is a known issue and a patch-fix is in the works.

Apologies for the inconvenience, will get that update out ASAP.
