UNet IndexOutOfRangeException: NetworkReader:ReadBytes out of range error when spawning a 2nd Player
I have a multiplayer game and when I launch the host, I can select a character and he spawns with no problem. But when I try and join the game on another (local) client, the character gets created in the scene at (0,0,0) but then I get this fatal error every time:

I've been trying to track down exactly where this happens but to no avail.
Note: I am using a package from the asset store that extends NetworkManager.cs
Edit: I'm also getting this error when I run the game. I'm not sure if it has anything to do with it.
NetworkManager detected a script reload in the editor. This has caused the network to be shut down.
UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()
I can't imagine this is anything but a bug. I managed to fix it by overriding the OnDeserialize() method in my Player class that extends the NetworkBehaviour class.
public override void OnDeserialize(NetworkReader reader, bool initialState)
{
base.OnDeserialize(reader, initialState);
}
And the error is no longer appearing.
This bug is still around in 2017.3 and this fix still works, thanks.
THAN$$anonymous$$ YOU! I have been working on this issue for several days now.
Hmm... I just started getting this error today and I am on 5.4.2f2
I have no OnDeserialize ( NetworkReader... ) in my project
$$anonymous$$e three. Still hoping somebody with know-how finds us.
For me this ended up being because I had a networked gameObject within the DontDestroyOnLoad scene. This is apparently not supported and everything must be within the active scene.
I was having the same problem when I read the NetworkMessage use code like this:
CustMsg msg = netMsg.ReadMessage<CustMsg>();
Solve the problem by adding the following code in front
netMsg.reader.SeekZero();
CustMsg msg = netMsg.ReadMessage<CustMsg>();
Thank you so much for posting this! i have been having troubles for more than 3 months and this solved every thing, thank you!!
If you have this issue, try to disable the network animator. This worked for me !
For those of you coming to this forum looking for answers...
Using 5.3.x this was a potential fix, however with 5.4 I have came to the realization that this actually causes the IndexOutOfRangeException: NetworkReader:ReadBytes error to occur.
So just to reiterate, those experiencing the issue in 5.4 should get rid of any
public override void OnDeserialize(NetworkReader reader, bool initialState) { base.OnDeserialize(reader, initialState); }
calls they may have throughout the project.
Hope this helps!
