[Python] Facebook comments

So i have this app that i use to get comments from a facebook post, however i encounter a problem when there are more than 300 comments. As some comments turn into random numbers? Example. At first i thought that maybe i am making API requests too often, thus i added 10s waiting time. However it does not seem to help. I would be grateful if you have any ideas as to why this is. Thank you in advance

import json
import time
import pandas as pd

ACCESS_TOKEN = "xx"
POST_ID = "xx"

# main function to get comments
def get_all_comments(post_id, limit=1000):
comments = []
url = f"https://graph.facebook.com/v22.0/{post_id}/comments?fields=id,message,from&limit=50&access_token={ACCESS_TOKEN}"

while url:
response = requests.get(url)
data = response.json()

if "data" in data:
for comment in data["data"]:
comment_id = comment.get("id")
commenter_name = comment.get("from", {}).get("name", "Nežinomas komentuotojas")
comment_message = str(comment.get("message", "Nėra komentaro"))

comments.append({"Vartotojas": commenter_name, "Komentaras": comment_message})

# Stopping when gets the amount of comments equal to limits
if len(comments) >= limit:
return comments

paging = data.get("paging", {})
cursor = paging.get("cursors", {}).get("after", None)
if cursor:
time.sleep(10)
url = f"https://graph.facebook.com/v22.0/{post_id}/comments?fields=id,message,from&limit=50&after={cursor}&access_token={ACCESS_TOKEN}"
else:
url = None

return comments


comments = get_all_comments(POST_ID, limit=1000)

# Saving in JSON
with open("comments_from_page.json", "w", encoding="utf-8") as file:
json.dump(comments, file, ensure_ascii=False, indent=4)

print(f" Iš viso gauta {len(comments)} komentarų.")

# Saving in excel
df = pd.DataFrame(comments)
df.to_excel("comments_from_page.xlsx", index=False, engine='openpyxl')

print("Komentarai sėkmingai perkelti į 'comments_from_page.xlsx'.")
