Issue with downloading tweets from twitter api (401 Unauthorized)

Question

I am having issues with my code as it was working last week with no issue and I could catch 800 tweets from Planet Fitness. I believe it has to do with my JSON file with my access and consumer keys for the api however I regenerated all keys and the 401 error still occurs. How should I fix this to download the tweets from that user?

Here is my code:

#getting tweets from planet fitness from before 2022 Superbowl Ad
username = "PlanetFitness"
tweets = []
fetchedTweets = api.user_timeline(screen_name = username, count = 200)
tweets.extend(fetchedTweets)
lastTweetInList = tweets[-1].id - 1

while (len(fetchedTweets) > 0):
        fetchedTweets = twitterAPI.user_timeline(screen_name = username, count = 200, max_id = lastTweetInList)
        tweets.extend(fetchedTweets)
        lastTweetInList = tweets[-1].id - 1
        print(f"Catched {len(tweets)} tweets so far.")

Here is the error:

---------------------------------------------------------------------------

      5 tweets.extend(fetchedTweets)
      6 lastTweetInList = tweets[-1].id - 1
