Script to export gltf fails with "AttributeError: 'NoneType' object has no attribute 'scene'"

Question

I have this script that works on Blender 3.1, to convert a directory with fbx files to glb. I'm trying to using it in Blender 3.2.2, but the scripting is failling with:

"AttributeError: 'NoneType' object has no attribute 'scene'"

This error happens on the line were the glb file is being exported. But I could not understand why, if its a missing parameters, or something that I need to set in the context

The script is bellow

CONVERT_DIR = "/DIR"

import os

def file_iter(path, ext):
    for dirpath, dirnames, filenames in os.walk(path):
        for filename in filenames:
            ext = os.path.splitext(filename)[1]
            if ext.lower().endswith(ext):
                yield os.path.join(dirpath, filename)

import bpy


def reset_blend():
    bpy.ops.wm.read_factory_settings(use_empty=True)

def convert_recursive(base_path):
    for filepath_src in file_iter(base_path, ".fbx"):
        filepath_dst = os.path.splitext(filepath_src)[0] + ".glb"

        print("Converting %r -> %r" % (filepath_src, filepath_dst))

        reset_blend()

        bpy.ops.import_scene.fbx(filepath=filepath_src)

        ctx = bpy.context.copy()
        
        ctx['active_object'] = None

        bpy.ops.export_scene.gltf(ctx,export_format="GLB",filepath=filepath_dst)


if __name__ == "__main__":
    convert_recursive(CONVERT_DIR)

The stacktrace:
