List for Schema use Field alias

[becory]

Hi, I have some problem when I first time to using this amazing fast REST framework.

I have a schema to using the alias Field for get an Item.

class ItemSerializer(Schema):
    category: str = Field(None, alias="category_schema.category.name")
    invoice_date: str = Field(None, alias="form.invoice_date")
    description: str = Field(None, alias="form.description")
    amount: int = Field(None, alias="form.amount")

But when I put schema into ItemList. It's crash.

class ItemListSerializer(Schema):
    item_list = List[ItemSerializer] = []

TypeError: '_GenericAlias' object does not support item assignment

Does any way to resolve this problem?
