NetworkMessage Class for Error

Hey folks,

I'm trying to build a simple chat client / server setup as PoC for an greater networking project.

However, for that im using the NetworkServer simple with following initialisation code:

 networkServer = new NetworkServerSimple();
         
 networkServer.RegisterHandler (MsgType.Connect, OnClientConnected);
 networkServer.RegisterHandler (MsgType.Disconnect, OnClientDisconnected);
 networkServer.RegisterHandler (MsgType.Error, OnError);
 networkServer.RegisterHandler (ChatID, OnChatMessage);
         
 networkServer.Listen(port);
         
 Debug.Log("host created:" + networkServer.serverHostId);

The Handler Methods are defined as followed:

 private void OnClientConnected(NetworkMessage networkMessage)
     {
         Debug.Log("client connected");
     }
 
     private void OnClientDisconnected(NetworkMessage networkMessage)
     {
         Debug.Log("client disconnected");
     }
 
     private void OnError(NetworkMessage networkMessage)
     {
     }

My problem is the OnError-Handler. Each Handler has the NetworkMessage as parameter and I want to read that message in case of an error to display this error in my ui. But for that I need to know what Message the NetworkMessage is so I can read it correctly with

 var msg = networkMessage.ReadMessage<???>()

Can anyone tell me the NetworkMessage class of MsgType.Error and maybe of the other two MsgTypes (Connect/Disconnect)?

Thanks in advance, Patrick
