   The same seems to be fixed from the below workaround:
   https://github.com/apache/arrow/blob/1d904d64ba89835fa6587ed08121a06df51f92b4/python/pyarrow/pandas_compat.py#L511
   ```
   def _get_index_level_values(index):
       n = len(getattr(index, 'levels', [index]))
       if isinstance(index, _pandas_api.pd.MultiIndex):
           return [index.levels[i] for i in range(n)]
       else:
           return [index.get_level_values(i) for i in range(n)]
   ```
