Project Body Faces Into Sketch

Dears, I have start to develop a VBA code, that should: 1- ask user to select a face from any bodies in the current CATPART. 2- once done VBA should extract that surface in a geometrical set and create 3 points on the contour of that surface. 3- based on these points, create a Plan and lastly project that surface contour inside a sketch.

below my code, it doesn't work. it displays type mismatch without specify were .

picture describe more or less what I want. NB: the catpart may contain complex shape, that's way the extracted surface needs to be in tangency

You can project the face/extract directly into the sketch, so no additional projection and creating of lines is necessary.
Here a shorter example. I used one of the OriginElement for the sketch.

Sub CATMain()
    Dim partDocument As PartDocument
    Dim part1 As Part
    Dim selection1 As Selection
    Dim hybridShapeFactory As Object
    Dim hybridBody As hybridBody 
    Dim reference1 As Reference
    Dim hybridShapeExtract As hybridShapeExtrac
    Dim sketch As Sketch
    Dim sketches As Sketches
    Dim InputObjectType(0)
    Dim Result as String

    ' Initialize CATIA Document and Part
    Set partDocument = CATIA.activeDocument
    Set part1 = partDocument.part
    Set selection1 = partDocument.selection
    
    ' Clear previous selections
    selection1.Clear

    ' Select the face
    InputObjectType(0)="PlanarFace" 
    result = selection1.SelectElement2(InputObjectType, "Select a face", False)
    
    ' Check the type of the result and compare accordingly
    If result <> "Normal"  Then
        MsgBox "No valid face selected. Exiting."
        Exit Sub
    End If
    
    ' Get the selected face
    If selection1.Count = 0 Then
        MsgBox "No face selected. Exiting."
        Exit Sub
    End If

    ' Create a reference from the face
    Set reference1 = selection1.Item(1).Reference
    
    ' Create the Hybrid Shape Factory and Hybrid Body
    Set hybridShapeFactory = part1.hybridShapeFactory
    Set hybridBody = part1.hybridBodies.Add
    
    ' Extract the surface from the face
    Set hybridShapeExtract = hybridShapeFactory.AddNewExtract(reference1)
    hybridShapeExtract.Name = "ExtractedSurface"
    hybridBody.AppendHybridShape hybridShapeExtract
    part1.Update
    
    ' Create a sketch on on YZ plane
    Set oRefPlane = part1.OriginElements.PlaneYZ
    Set sketches = hybridBody.HybridSketches
    Set sketch = sketches.Add(oRefPlane)

    ' Open the sketch
    Dim factory2D As Object
    Set factory2D = sketch.OpenEdition()

    'project extract in sketch
    Dim oProjection
    Set oProjection = factory2D.CreateProjection(hybridShapeExtract)
    
    ' Close the sketch edition
    sketch.CloseEdition
    
    ' Update the part
    part1.Update
    
    MsgBox "Surface extracted and sketch projected successfully!"

End Sub
