How Does the api.get_retweeter_ids() Actually Work (Tweepy Python)?

I am really new to twitter api, and I've been trying to get a list of IDs of everyone that retweeted a specific tweet. After several attempts i can't get the 'api.get_retweeter_ids' to get every id. It always seems to get a few. I know there is a limit of 100 per request, but the function just ends there after getting around 50-90 IDs on a tweet with 30k retweets or so.

Here is my code

def get_user_ids_by_retweets(tweetid):
    retweeters_ids = []
    for i, _id in enumerate(tweepy.Cursor(api.get_retweeter_ids, id=tweetid).items()):
        retweeters_ids.append(_id)
        print(i, _id)
    df = pd.DataFrame(retweeters_ids)
    # print(df)
    return retweeters_ids

    bearer_token ="*************************"
    client = tweepy.Client(bearer_token=bearer_token)

    listUser = []
    # get first paging retweet users
    retweeters = client.get_retweeters(id=tweet_id)
    for retweeter in retweeters.data:
        listUser.append({
            "name": retweeter.name,
            "id": retweeter.id,
            "username": retweeter.username
        })    
    next_token = retweeters.meta['next_token']

    # get til end of paging retweet users
    while next_token != None:
        retweeters = client.get_retweeters(id=tweet_id, pagination_token=next_token)
        if retweeters.data is not None:
            for retweeter in retweeters.data:
                listUser.append({
                    "name": retweeter.name,
                    "id": retweeter.id,
                    "username": retweeter.username
                })    
            next_token = retweeters.meta['next_token']
        else:
            next_token = None

    return listUser


def obj_dict(obj):
    return obj.__dict__

tweet_id="1582388225049780230"

listUser = get_user_ids_by_retweets(tweet_id)
print(json.dumps(listUser, indent=4, default=obj_dict))

Result

Main Idea

Get tweeter API return limited number of tweeters with next_token. It can be next paging's tweeter by assign to pagination_token. It can be all of tweeter until 'next_token` is null.

So #1 and #2 get two tweeters with next_token , those sum tweeters are same as #3 tweeters.

import tweepy

bearer_token ="*************************"

client = tweepy.Client(bearer_token=bearer_token)

tweet_id="1582388225049780230"
print("#1 -------- Get first two tweeter -------------------------")
retweeters = client.get_retweeters(id=tweet_id, max_results=2)

print("#2 -------- Show Meta --------------------")
print(retweeters.meta)
print(" ")
print("#3 -------- print two -------------------------")
for retweeter in retweeters.data:
    print(retweeter.name, " -> ",retweeter.id,",",retweeter.username)
print(" ")

print("#4 ---------Get Next two tweeter ---------------------------")
retweeters = client.get_retweeters(id=tweet_id, pagination_token=retweeters.meta['next_token'] ,max_results=2)
print(retweeters.meta)
print(" ")
print("#5 -------- print two -------------------------")
for retweeter in retweeters.data:
    print(retweeter.name, " -> ",retweeter.id,",",retweeter.username)
print(" ")

print("#6 --- Get First four tweeter ==  are same #1 + #2 ---------")
retweeters = client.get_retweeters(id=tweet_id, max_results=4)
print(" ")
print("#7 -------- print four -------------------------")
for retweeter in retweeters.data:
    print(retweeter.name, " -> ",retweeter.id,",",retweeter.username)

$ python retweet.py
