client.tasks.list with fields = 'all' fails on comment_authors

[LeoVrana]

Hi!

I am on Label Studio enterprise, on version 1.0.5. I am trying to get annotation data for a project via the SDK + API. The problem is that when I iterate over tasks, any task with a comment inevitably throws a pydantic ValidationError:

>>> tasks = ls.tasks.list(project=project_id, fields='all')
>>> for t in tasks:
...     pass
... 
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

Let me know if there is any other information you might need.
