raise sa_exc.ArgumentError(
sqlalchemy.exc.ArgumentError: Type annotation for "Order.items" can't be correctly interpreted for Annotated Declarative Table form. ORM annotations should normally make use of the Mapped[] generic type, or other ORM-compatible generic type, as a container for the actual type, which indicates the intent that the attribute is mapped. Class variables that are not intended to be mapped by the ORM should use ClassVar[]. To allow Annotated Declarative to disregard legacy annotations which don't use Mapped[] to pass, set "allow_unmapped = True" on the class or a superclass this class.
