Tweepy - 如何将用户添加到特定列表

Question

我正在尝试在一次运行中制作多个动作，转发带有特定主题标签的推文，并将用户添加到列表（已创建的列表）。我收到错误消息

[{'code'：108，'message'：'找不到指定的用户。'}]

# Import Tweepy, sleep, credentials.py
import tweepy
from time import sleep
from credentials import *

# Access and authorize our Twitter credentials from credentials.py
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = tweepy.API(auth)

for tweet in tweepy.Cursor(api.search, q=('#ECM OR SPFx OR SharePoint'), lang='en').items(6):
    try:
        # Add \n escape character to print() to organize tweets
        print('\nTweet by: @' + tweet.user.screen_name)

        # Retweet tweets as they are found
        tweet.retweet()
        print('Retweeted the tweet')

        #Add to list
        api.add_list_member(screen_name='tweet.user.screen_name', slug='ListSlugName', owner_screen_name='@MyName')

        sleep(5)

    except tweepy.TweepError as e:
        print(e.reason)

    except StopIteration:
        break
