Error Saving File After Creating A Frame with FrameBench Manager

[andres-hurtado-lopez]

Hi:

When I try to draw a simple frame using the FrameBench Manager with a sketch that simply uses a rectangle and a custom profile built using the "Insert Sections" I get and error trying to save the file with the structure created:

22:27:49  PropertyPythonObject::toString(): failed for <class 'fFeatures.ViewProviderFrameBranch'>
22:27:49  Traceback (most recent call last):
  File "/tmp/.mount_freecaisJjZw/usr/lib/python3.10/json/__init__.py", line 231, in dumps
    return _default_encoder.encode(obj)
  File "/tmp/.mount_freecaisJjZw/usr/lib/python3.10/json/encoder.py", line 199, in encode
    chunks = self.iterencode(o, _one_shot=True)
  File "/tmp/.mount_freecaisJjZw/usr/lib/python3.10/json/encoder.py", line 257, in iterencode
    return _iterencode(o, 0)
  File "/tmp/.mount_freecaisJjZw/usr/lib/python3.10/json/encoder.py", line 179, in default
    raise TypeError(f'Object of type {o.__class__.__name__} '
<class 'TypeError'>: Object of type ViewProviderDocumentObject is not JSON serializable

I'm using freecad 0.21.2 from an Appimage and my computer setup is the following:
