Profile object does not deserialize `core_attributes` correctly (?)

I am trying to get some profiles by id and I cannot figure out if there is a bug in this library or if I am not using it correctly, but when I get a profile with a call like:

profile_client = connection.clients_v6_0.get_profile_client()
a_profile = profile_client.get_profile(authenticated_user_id, details=True)

I see that data like the Avatar is coming back from the http request log

...
'Avatar': {'descriptor': {'attributeName': 'Avatar',
    'containerName': 'Core'},
   'value': {'value': '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',

    'isAutoGenerated': True},
   'timeStamp': '2020-12-09T16:53:10.5466667+00:00'},
...

but if I serialize the Profile object, I do not see anything

a_profile.as_dict()

...
{'core_attributes': {'DisplayName': {},
  'PublicAlias': {},
  'EmailAddress': {},
  'UnconfirmedEmailAddress': {},
  'CountryName': {},
  'TermsOfServiceVersion': {},
  'TermsOfServiceAcceptDate': {},
  'Avatar': {},
  'ContactWithOffers': {}},
...

and even if I get the Avatar object from a_profile.core_attributes, the object does not seem to contain anything.

Is there a problem with the library or I am not using it correctly?

Thanks a lot in advance e for your help.

Bắt đầu với lệnh gọi get_profile(..., details=True) và so sánh phản hồi HTTP đã được ghi log với a_profile.as_dict() và a_profile.core_attributes. Theo dõi cách các core_attributes được trả về, đặc biệt là Avatar, được biểu diễn trong quá trình giải tuần tự hóa; hoàn thành khi Profile được tuần tự hóa giữ nguyên các giá trị có trong phản hồi.
