B4R Question ESP32 and AsyncStreams

[Paradicsom]

Hi,
i need to establish a communication with Hardware-serial.
It is not possible to comile this little code.
Using:
- ESP32 DevModule,
- Arduino ide 2.3.10 (Updates for all Boards and librarys
- B4R 4.0

I hope somebody can help

#Region Project Attributes
    #AutoFlushLogs: True
    #CheckArrayBounds: True
    #StackBufferSize: 300
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'Public variables can be accessed from all modules.
    Public Serial1 As Serial
    'DFÜ mit Nextion
    Private SerialNative2 As Stream
    Private Stream1 As AsyncStreams
    
End Sub

#if C
//HardwareSerial Serial2(2); // second Hardware Port
HardwareSerial Serial2(2);
void SerialNative2(B4R::Object* unused) {
   ::Serial2.begin(9600);
  b4r_main::_serialnative2->wrappedStream = &::Serial2;
}
#end if



Private Sub AppStart
    Serial1.Initialize(115200)
    Log("AppStart")
    
    Dim s As String
    
    Log("Stream initialize")
    Stream1.Initialize(SerialNative2, "Nextion_NewData", "Nextion_Error")
    'Page 1 on Nextion
    s = JoinStrings(Array As String("page 1"))
    Stream1.Write(s.GetBytes).Write(Array As Byte(0xFF, 0xFF, 0xFF))
End Sub

Sub Nextion_NewData(Buffer() As Byte)

End Sub

Sub Nextion_Error(Buffer() As Byte)

End Sub

I get everytime this error-codes (also in older versions):

check this error sub :

Sub Nextion_Error

End Sub

sub is SubVoidVoid => normally no parameter
