Cannot access game attributes in a loop

[cmnemoi]

So, given this code (for reproducibility) :

import srcomapi, srcomapi.datatypes as dt
import pandas as pd

api = srcomapi.SpeedrunCom(); api.debug = 1
test_df = pd.DataFrame(['Castlevania: Aria of Sorrow','Pokémon: Yellow'],columns=['Game'])
nb_games = len(test_df)

lb_per_game = []

#getting the game for each name
for i in range(nb_games):
    try: 
      test_df.loc[i,'SRC_game'] = api.search(srcomapi.datatypes.Game, {"name": test_df.loc[i]['Game']})[0]
    except IndexError:
      pass

#collecting leaderboards for each game
for i in range(nb_games):
    lb = {}
    for category in test_df.loc[i,'SRC_game'].categories:
      if not category.name in lb:
        lb[category.name] = {}
      if category.type == 'per-level':
        pass
      # if category.miscellaneous:
      #   pass
      else:
        lb[category.name] = dt.Leaderboard(api, data=api.get("leaderboards/{}/category/{}?embed=variables".format(test_df.loc[i,'SRC_game'].id, category.id)))
    lb_per_game.append(lb)

This piece of code works :

platform = lb_per_game[0]['Soma Any%'].game.__getattr__('platforms')[0]
 print(platform)

But this one does not :

for i in range(2):
  game = lb_per_game[0]['Soma Any%'].game
  platform = game.__getattr__('platforms')[0]
  print(platform)

It raises a Type Error at the second time you enter the loop on second line :

object of type 'Platform' has no len()
  File "C:\Users\charl\OneDrive\Documents\Projects\OWREstimator\srcdata.py", line 68, in <module>
    platform = game.__getattr__('platforms')[0]

By inspecting the debugger, it seems the game.platforms attribute equals to this at this moment :
'Traceback (most recent call last):\n File "c:\\Users\\charl\\.vscode\\extensions\\ms-python.python-2021.6.944021595\\pythonFiles\\lib\\python\\debugpy\\_vendored\\pydevd\\_pydevd_bundle\\pydevd_resolver.py", line 193, in _get_py_dictionary\n attr = getattr(var, name)\n File "C:\\Users\\charl\\miniconda3\\lib\\site-packages\\srcomapi\\datatypes.py", line 46, in __getattr__\n if type(self.data[attr]) is list and len(self.data[attr]) > 0 and len(self.data[attr][0]) == 8:\nTypeError: object of type \'Platform\' has no len()\n'
(same for all not null attributes)
