协助修复 Telethon 抓取代码，总是返回错误

如何解决协助修复 Telethon 抓取代码，总是返回错误

使用 python pip install telethon 安装 Telethon scraper 后 并运行下面的代码

from telethon.sync import TelegramClient
api_id = 7072283
api_hash = 'Oadf8d756f690ca4e02d0yuy8c80c3042'
phone = '[phone]'
client = TelegramClient(phone,api_id,api_hash)

client.connect()
if not client.is_user_authorized():
   client.send_code_request(phone)
   client.sign_in(phone,input('Enter the code: '))


from telethon.tl.functions.messages import GetDialogsRequest
from telethon.tl.types import InputPeerEmpty
chats = []
last_date = None
chunk_size = 200
groups=[]

result = client(GetDialogsRequest(
            offset_date=last_date,offset_id=0,offset_peer=InputPeerEmpty(),limit=chunk_size,hash = 0
        ))
chats.extend(result.chats)

我总是收到这个错误

Traceback (most recent call last):

    result = await future
telethon.errors.rpcerrorlist.AuthKeyUnregisteredError: The key is not registered in the system (caused by GetDialogsRequest)

请帮帮我 注意我使用的是运行 ubunto 20.4 的 linux 系统
