[Python] How to create list of UUID field

I need to create a list of UUID field:

from uuid import UUID
from sqlalchemy import UUID as saUUID


class Subsection(LastActionModelMixin, Base):
__tablename__ = "help_subsection"

id: Mapped[int] = mapped_column(primary_key=True, autoincrement=True)
document_ids: Mapped[list[UUID]] = mapped_column(ARRAY(saUUID), default_factory=list)


The code above produces exception:

sqlalchemy.exc.ArgumentError: Attribute 'document_ids' on class <class'app.models.help.Subsection'> includes dataclasses argument(s): 'default_factory' but class does not specify SQLAlchemy native dataclass configuration.
​

How to fix the error?
