Loop Cut and Slide using Python not working I'm trying to use loop-cut and slide in Python.

I've tried the following:
Loop cut and slide using python script in blender
How do I override context for bpy.ops.mesh.loopcut?
Loop Cut and Slide using Python

The best I can get is "no error and no loop cut".  -_-
(new_outsideWall is a procedurally created object)

The following code selects the correct object, enters 3D view, goes to edit mode, does NOT generate a loop cut, exits edit mode and returns to previous screen view.  No error at all.

I know it has something to do with either bpy.ops.mesh not targeting the correct mesh, or override not being in the right context. But being a complete noob, I have no idea how to fix, nor can I locate the answer.

Thanks.

In case you're wondering, I'm trying to create a "random building generator" and this is the adjustable cutout for the window textures.  ^_^

old_type = bpy.context.area.type
bpy.context.area.type = 'VIEW_3D'
bpy.context.view_layer.objects.active = new_outsideWall
new_outsideWall.select_set(True)
bpy.ops.object.editmode_toggle()
def view3d_find( return_area = False ):
    # returns first 3d view, normally we get from context
    for area in bpy.context.window.screen.areas:
        if area.type == 'VIEW_3D':
            v3d = area.spaces[0]
            rv3d = v3d.region_3d
            for region in area.regions:
                if region.type == 'WINDOW':
                    if return_area: return region, rv3d, v3d, area
                    return region, rv3d, v3d
    return None, None

region, rv3d, v3d, area = view3d_find(True)

override = {
    'scene'  : bpy.context.scene,
    'region' : region,
    'area'   : area,
    'space'  : v3d
}
bpy.ops.mesh.loopcut_slide(
    override,
    MESH_OT_loopcut = {
        "number_cuts"           : 1,
        "smoothness"            : 0,     
        "falloff"               : 'INVERSE_SQUARE',  # Was 'INVERSE_SQUARE' that does not exist
        "edge_index"            : 1,
        "mesh_select_mode_init" : (True, False, False)
    },
    TRANSFORM_OT_edge_slide = {
        "value"           : 0,
        "mirror"          : False, 
        "snap"            : False,
        "snap_target"     : 'CLOSEST',

        "release_confirm" : False,
        "use_accurate"    : False
    }

bpy.ops.object.editmode_toggle()
bpy.context.area.type = old_type
if you're still interested, I've found the solution to your problem.
I had more or less the same script for Blender 2.79 and run in the same issue in Blender 2.8x.
All you have to do is adding the variable &quot;object_index&quot; : 0 in MESH_OT_loopcut
