[Python] Fetching live comments on Facebook Video turn names to "None"

i'm testing out this code to fetch video comments on my Facebook Page but the commenter's names turn to None, but when I comment on it using my own Page it catches the name. How could it be?

#!/usr/bin/env python3
import requests, json, urllib.parse

VIDEO_ID = "videoId"
PAGE_TOKEN = "pagetoken"

# Build the URL with query params using urllib.parse
params = {
"fields": "id,from{name},message,created_time",
"access_token": PAGE_TOKEN,
"order": "reverse_chronological",
"limit": 25,
}
url = f"https://graph.facebook.com/v20.0/{VIDEO_ID}/comments?{urllib.parse.urlencode(params)}"

try:
r = requests.get(url, timeout=10)
data = r.json()
except Exception:
print("Non-JSON response:", r.text)
raise

# Print results in a loop (instead of raw JSON dump)
if "data" in data:
for c in data["data"]:
cid = c.get("id")
user = c.get("from", {}).get("name")
msg = c.get("message", "")
ts = c.get("created_time", "")
print(f"[{ts}] {user}: {msg} (id: {cid})")
else:
print("⚠️ API returned:", json.dumps(data, indent=2))
