Why can't I delete multiple tweets with this code? Python tweepy – Twitter API

I am trying to use this code to delete 550 tweets from my account, as I want to use it as my personal account again without the tweets from my bots:

import tweepy
import json

auth = tweepy.OAuthHandler("consumer_key", "consumer_secret")

auth.set_access_token("access_token", "access_token_secret")

api = tweepy.API(auth)

screen_name = "YOUR_TWITTER_HANDLE"

timelines = api.user_timeline(screen_name, count = 550, include_rts = False)

for status in timelines:
    tweetid = status._json
    api.destroy_status(tweetid)

But every time I run it, I get this error:

tweepy.error.TweepError: [{'message': 'Application cannot perform write actions. Contact Twitter Platform Operations through https://support.twitter.com/forms/platform', 'code': 261}]

When I print tweetid, it is successfully grabbing all my tweets. I can also tweet normally using api.update_status, so why is this not working? What am I doing wrong?
