Friendship.search方法还能用吗？

运行
```
contact: Contact = await self.Friendship.search( phone='183********' )
await contact.ready()
```
报这个错误
```
2022-09-02 13:54:14,474 - FriendShip - INFO - search() <<class 'abc.Friendship'>, None, 183********>
2022-09-02 13:54:14,976 - Wechaty - ERROR - internal error <'NoneType' object has no attribute 'ready'>
```
我运行Friendship.search就没成功过，想知道这个功能现在还能用吗？还是说不稳定？
