[Closed] Unknown property: "Edit_Poly" error

A problem that has always bothered newbies, I want to use maxscript to give different compositematerial basematerial:(standard diffuse:(color 150 255 150)) to triangles and compositematerial basematerial:(standard diffuse:(color 150 150 255))pentagons in an obj file. But when I convert it to a mesh object, the listener says: Unknown property: “Edit_Poly” in $Editable_Mesh: 4^3 -3-3-3^^4 obj @ [0.000000, 0.000000, 0.000000]. How do I solve it? Thank you for your answer.

obj_files = getFiles “*.obj”
for f in obj_files do
(
–import file
if ( doesfileexist f ) do
importFile f #noPrompt using:Wavefront_Object

objfilename = getFilenameFile f

for geo in geometry 
	where ((geo.name == objfilename) or (matchPattern geo.name pattern:"3D_Object*") or (matchPattern geo.name pattern:"default*") or (matchPattern geo.name pattern:"*_obj")) do 
(
	--geo.name = (f as string) 
	pathaa = filterString (f as string) "\\"
	geo.name = pathaa[pathaa.count]
	geo.colorByLayer = false
	geo.pivot = [0,0,0]
				
	addModifier geo (unwrap_UVW())
				
	convertToMesh geo
	format "Object Name  : % | Class : %" (geo.name) (classof geo)	
	num2 = geo.NumFaces --integer
    triangleMaterial = compositematerial basematerial:(standard diffuse:(color 150 255 150))
	
	pentagonMaterial = compositematerial basematerial:(standard diffuse:(color 150 150 255))
	
	-- Loop through all faces in the geometry
	for i = 1 to num2 do
	(
		if (geo.Edit_Poly.getFaceDegree i) == 3 then
			(
				-- Select the triangle face and assign the triangle material
				geo.Edit_Poly.SelectFaces #{i}
				geo.Edit_Poly.SetFaceMaterial triangleMaterial
				geo.Edit_Poly.SetFaceColor (color 0 0 0)
			)
		if (geo.Edit_Poly.getFaceDegree i) == 5 then
			(
				-- Select the pentagon face and assign the pentagon material
				geo.Edit_Poly.SelectFaces #{i}
				geo.Edit_Poly.SetFaceMaterial pentagonMaterial
				geo.Edit_Poly.SetFaceColor (color 0 0 0)
			)
	)
