Unity UNET Multiplayer Chatroom - (Need Help With 1 Line)

Hey guys! I’m developing a UNET Multiplayer Chat system, all is going well apart from one command.
I keep getting an error no matter how I try format the line, I’m just a little under educated with this one command, if anyone can help me I would be very grateful.

ERROR I GET:
Assets/Scripts/Input.js(34,81): BCE0024: The type ‘Object’ does not have a visible constructor that matches the argument list ‘(String)’.

My Code (JAVA)

var mainChatScript : mainChat;
var currentMessage = "";
var username = "";
private var pt2 = ":  ";
var fullName = "";

function Awake()
{
	mainChatScript = GameObject.Find("Server").GetComponent(mainChat);
}

function Update ()
{
	if(networkView.isMine)
	{
		currentMessage = username + pt2 + currentMessage;
	}
}

function OnGUI()
{
	GUILayout.Space(2);
	GUILayout.BeginHorizontal(GUILayout.Width(Screen.width));
	GUILayout.BeginVertical ("box");
	currentMessage = GUILayout.TextField(currentMessage);
	username = GUILayout.TextField(username, 12);
	
	if(GUILayout.Button("SEND")) 
	{
		if(!String.IsNullOrEmpty(currentMessage.Trim()))
		{
			networkView.RPC("SendMessage", RPCMode.AllBuffered, new Object[currentMessage]);
			currentMessage = String.Empty;
		}
	}
	
	GUILayout.EndVertical();
	GUILayout.EndHorizontal();
}

@RPC
public function SendMessage(string, message)
{
	mainChatScript = GameObject.Find("Server").GetComponent(mainChat);
	mainChatScript.list.Add(message);
}

It’s true, the Object type does’t have a constructor that takes a string as a argument/parameter.

Also the function SendMessage was defined oddly, fixed that.

 var mainChatScript : mainChat;
 var currentMessage = "";
 var username = "";
 private var pt2 = ":  ";
 var fullName = "";
 
 function Awake()
 {
     mainChatScript = GameObject.Find("Server").GetComponent(mainChat);
 }
 
 function Update ()
 {
     if(networkView.isMine)
     {
         currentMessage = username + pt2 + currentMessage;
     }
 }
 
 function OnGUI()
 {
     GUILayout.Space(2);
     GUILayout.BeginHorizontal(GUILayout.Width(Screen.width));
     GUILayout.BeginVertical ("box");
     currentMessage = GUILayout.TextField(currentMessage);
     username = GUILayout.TextField(username, 12);
     
     if(GUILayout.Button("SEND")) 
     {
         if(!String.IsNullOrEmpty(currentMessage.Trim()))
         {
             networkView.RPC("SendMessage", RPCMode.AllBuffered, currentMessage); // don't need to set as object, also don't need to set an non-existing indexer
             currentMessage = String.Empty;
         }
     }
     
     GUILayout.EndVertical();
     GUILayout.EndHorizontal();
 }
 
 @RPC
 public function SendMessage(message : string) // your parameters/argument was wrongly defined as "string, message"
 {
     mainChatScript = GameObject.Find("Server").GetComponent(mainChat);
     mainChatScript.list.Add(message);
 }
