Still good to go on Blender 3.3.2

Hi, I tried both versions of the code listed above but the exported objs are still the same as the basis model. I'm currently using Blender 3.3.4. Is there an update to work with this version? Thank you in advance for any info anyone can provide.

Its showing bpy.ops.export_scene.obj error while exporting shapekeys

bpy.ops.wm.obj_export(filepath = objPath,export_selected_objects=True,export_uv=True,scaling_factor=1.0,apply_modifiers=True,export_materials=False)

Thanks! It works. I mean, I get the basic things working. Need to test this with complex UV Maps.

In 4.2.2 I had to change the expression for scaling back to global_scale:
bpy.ops.wm.obj_export(filepath = objPath,export_selected_objects=True,export_uv=True,global_scale=1.0,apply_modifiers=True,export_materials=False)
