B4J Question SendEventToServer isn't working !

[jinyistudio]

I can runfunction to client.
when I use SendEventToServer in the client(b4j app) Why server side always give me Runtime Exception:Invilid event name : fromclient1 ?

jserver V3.0
jwebsocketclient V1.10

client side code

Sub wsc_connected
    Log($"gate connected. ${Main.gateaddr}"$)
    SendEventToServer("fromclient1",CreateMap("test":1))
End Sub

Public Sub SendEventToServer(Event As String, Data As Map)
    Dim m As Map
    m.Initialize
    m.Put("type", "event")
    m.Put("event", Event)
    m.Put("params", Data)
    Dim jg As JSONGenerator
    jg.Initialize(m)
    wsc.SendText(jg.ToString)
End Sub

Private Sub wsc_TextMessage(msg As String)
    Try
        Dim jp As JSONParser
        jp.Initialize(msg)
        Dim m As Map = jp.NextObject
        Dim etype As String = m.get("etype")
        Dim params As List = m.get("value")
        Dim event As String = m.get("prop")
      
        If etype = "runFunction" Then
            CallSub2(Me, "wsc_"  & event, params)
          
        Else If etype = "runFunctionWithResult" Then
            Dim data As Map = CallSub2(Me, "wsc_" & event, params)
            Dim jg As JSONGenerator
            Dim m2 As Map : m2.Initialize
            m2.Put("type", "data")
            m2.Put("data", data)
            jg.Initialize(m2)
            wsc.SendText(jg.ToString)
          
        End If
    Catch
        Log("TextMessage Error: " & LastException)
    End Try
End Sub

server side code

'WebSocket class
Sub Class_Globals
    Private     ws As WebSocket
    Private     item As Map
    Private     timer1 As Timer
End Sub

Public Sub Initialize
    timer1.Initialize("timer1",500)
    timer1.Enabled=False
End Sub

Private Sub WebSocket_Connected (WebSocket1 As WebSocket)
    ws = WebSocket1 
    Log($"Device connected. ${ws.UpgradeRequest.RemoteAddress}"$) 
End Sub

Private Sub WebSocket_Disconnected
    Log($"Device disconnected."$)
End Sub

Sub fromclient1(Params As Map)
    Log("Device message: ")
End Sub

Hi,It is OK. change fromclient1 to from_client

client side

wsc.SendEventToServer("from_client",CreateMap("test":1))

server side

Sub from_client(Params As Map)
    Log("Device message: ")
End Sub
