Unable to determine the file's size.

[logicli0n]

from sqlalchemy_file import FileField
class A(Base): file: Mapped[dict] = mapped_column(FileField, nullable=True) files = relationship( "B", back_populates="homework", passive_deletes=True, lazy="joined" )

class B(Base): a_id:Mapped[int] file: Mapped[dict] = mapped_column(FileField, nullable=True) a = relationship("A", back_populates="files")

fields = [ IntegerField(name="id", read_only=True), HasOne("document", identity="document", required=True), StringField("title"), TextAreaField("description"), TextAreaField("requirement"), FileField(name="file"), ListField( field=CollectionField( "files", fields=[ IntegerField(name="id", read_only=True), FileField(name="file"), ] ) ) ]

Когда добавляю файл внутри ListField дает ошибку Unable to determine the file's size.
