My web app uses Pytchat module once a day to retrieve YouTube live stream information, but about 1 out of every 60 video IDs fail to retrieve, and this issue only occurs on Heroku.
I’ve searched extensively for common factors among the videos that cause errors with the YouTube API, but I couldn’t find any.

Here is my environment:

• Python 3.12.4
• Pytchat 0.5.5(latest)

Here is my script:

import pytchat
import requests, json

# Check if the API communication works
url = requests.get("http://api.aoikujira.com/kawase/json/usd")
text = url.text
json_currency = json.loads(text)
print(json_currency)
print("Successful in API communication")

ids = "g5vKkS19nq8,kHo37taBFP8,6IJpVVGIxno,LPI_FnuvfhE,dWhmdgpeBts,NXcmsY5iXkw,ECATLuOt1AE"
ids = ids.split(",")

# To view the error, please run this code in heroku server.
# chat = pytchat.create(video_id=ids[0],interruptable=False)

# Try to create pytchat objects with wrong ids
for id in ids:
    try:
        chat = pytchat.create(video_id=id,interruptable=False)
        print("Successful in create")
    except:
        print("Failed in create")

Here is the error:

Traceback (most recent call last):

    raise IndexError

During handling of the above exception, another exception occurred:

The code worked not only in local, but also in colab: https://colab.research.google.com/drive/1npGihQ4KVHFn1tBMpAbY7HDFVsDk4CNW
