Blender Version
Broken: 2.91
Worked: 2.90.1

Short description of error

Traceback (most recent call last):

File "/Applications/Blender.app/Contents/Resources/2.91/scripts/addons/io_scene_gltf2/__init__.py", line 76, in on_export_format_changed
  operator = sfile.active_operator

AttributeError: 'NoneType' object has no attribute 'active_operator'
File "/Applications/Blender.app/Contents/Resources/2.91/scripts/addons/io_scene_gltf2/init.py", line 73, in on_export_format_changed

Exact steps for others to reproduce the error

- Export to gltf
- https://docs.blender.org/api/current/bpy.ops.export_scene.html

  basedir = os.path.dirname(bpy.data.filepath) # get the path where the blend file is located
  filepath = os.path.join(basedir, 'test.gltf')

    - BREAKS in Blender 2.91
- Expects to be called from UI

  bpy.ops.export_scene.gltf(
      export_format = 'GLTF_EMBEDDED',
      filepath = filepath,
      export_materials = True,
      export_cameras = True,
      export_lights = True,
      export_apply = True)
