`nextPageToken` doesn't work after one time works.

[quroom]

When I test this code,

import requests

channelId = 'UCLbOYoltlCD0LN06fSwKTsQ'

baseUrl = f'https://yt.lemnoslife.com/channels' # ?part=shorts&id={channelId}

nextPageToken = ''
index = 1
while True:
    params = {
        'part': 'shorts',
        'id': channelId,
    }
    if nextPageToken:
        params['pageToken'] = nextPageToken
    url = baseUrl
    #url = baseUrl + (f'&pageToken={nextPageToken}' if nextPageToken else '')
    #params = None
    response = requests.get(url, params = params).json()
    item = response['items'][0]
    print(f"page{index}.============================")
    for video in item['shorts']:
        print(video['title'])
    nextPageToken = item.get('nextPageToken')
    if not nextPageToken:
        break
    index+=1

It works well until page 2. But I get this error after page 2. What is the problem?

{
    "error": {
        "code": 400,
        "message": "Invalid pageToken"
    }
}

Thank you for reporting.

Does this code works only in local host? Or does this code has issue?

It works both on localhost and with the official YouTube operational API instance. See YouTube-operational-API/wiki/Glossary/0be0be6df7142cd10f8c0ce1504b1c0a82dbb416 for more details.

If you want it to use the official YouTube operational API instance, then change:

< URL = 'http://localhost/YouTube-operational-API/channels'
---
> URL = 'https://yt.lemnoslife.com/channels'

It's weird situation. Same code didn't work yesterday. Now it works very well.

You are relying on https://yt.lemnoslife.com website which I modified the source code according to above commit to solve the issue you reported, so it is normal that your end-user code works now without any change, it was a YouTube operational API instance server-side issue that I solved.

@Benjamin-Loison Now I understand what you are saying. Thanks for quick response.
