Exception: 无法创建复盘服务器

[listplot3d]

===简单描述===
用文档里的代码示例,做复盘报错:Exception: 无法创建复盘服务器
(信易账户在试用有效期内,执行请求普通的行情数据没有问题)

sys:1: RuntimeWarning: coroutine 'TqApi._notify_watcher' was never awaited

===重现步骤===
基于这里的代码:https://doc.shinnytech.com/tqsdk/latest/usage/replay.html?highlight=%E5%A4%8D%E7%9B%98,改成下面的代码,然后运行:

from datetime import date
from tqsdk import TqApi, TqReplay,TqAuth

api = TqApi(backtest = TqReplay(date(2019,12,23)), auth=TqAuth("listplotd", "123456"))
print("hello relay")
api.close()

复盘服务器目前不推荐使用，可以使用回测或模拟检验策略
