Objects in Python Client created with bravado don't have DICT object (__dict__ attribute missing)

[tdeboer-ilmn]

After creation of a PYTHON Client API with bravado, the various classes (like studies etc.) don't seem to have the correct definition, since they are missing the dict attribute:

from bravado.client import SwaggerClient

cbioportal = SwaggerClient.from_url(
    'https://www.cbioportal.org/api/api-docs',
    config={
        "validate_requests":False,
        "validate_responses":False,
        "validate_swagger_spec":False
    })

studies = cbioportal.Studies.getAllStudiesUsingGET().result()
sorted_studies = sorted(studies, key=lambda x: x.allSampleCount)
from pprint import pprint
pprint(vars(sorted_studies[-1])['_Model__dict'])

Results in this error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/tmp/ipykernel_3305572/1839231580.py in <module>
     12 sorted_studies = sorted(studies, key=lambda x: x.allSampleCount)
     13 from pprint import pprint
---> 14 pprint(vars(sorted_studies[-1])['_Model__dict'])

TypeError: vars() argument must have __dict__ attribute

Not sure if this is related with issue cBioPortal/icebox#298 but not likely.
