Django Rest Framework Serialiser错误->找不到字段

我从django后端的API中获取数据，并将数据序列化以获得所需的字段，然后将其发送到前端
该seriliaser

class EventSearchOutputSerialiser(Serializer):
    date_time = DateTimeField(source='dates.start.dateTime')
    icon = URLField(source='images.0.url', allow_null=True)
    event = CharField(source='name')
    genre = CharField(source='classifications.0.genre.name')
    venue = CharField(source='_embedded.venues.0.name')

字符串
所以基本上我在这里试图从嵌套字段中提取数据。
一个将被传递用于序列化的获取数据的例子。该数据从ticketmaster API获取。
