Description

When resolving a federation entity, the router may serialize Python objects for transmission purposes, but the entity on the receiving side may not deserialize or validate them.

For example, a datetime object may be automatically converted to an ISO-formatted string by the router, but the receiving side may not convert it back to a datetime object.

Original behavior:

@strawberry.federation.type(keys=["id"])
class Order:
    id: str
    create_at: datetime

>>> Order(id="some-order-id", create_at='2023-01-20T08:14:18.969624')
Order(id='some-order-id', create_at='2023-01-20T08:14:18.969624')

Excepted behavior:

@strawberry.federation.type(keys=["id"])
class Order:
    id: str
    create_at: datetime

>>> Order(id="some-order-id", create_at='2023-01-20T08:14:18.969624')
Order(id='some-order-id', create_at=datetime.datetime(2023, 1, 20, 8, 14, 18, 969624))
