You won’t get a pagination value if there are no more records.
So if a broadcaster has 50 subscribers but you set first 100.
Then you won’t get a pagination value.
If the caster in question does have more than 100 broadcasters and you are not getting a pagination value to use with this library it would suggest that there is a bug in the library and you might want to reach out to the libraries developers for guidance, it’s tough to give advice about specific libraries on the general help forum. (someone might notice and answer but might not and rather than leave you hanging I’m hoping to get you redirected to a more helpful place)
I believe they hold a presence on the Libraries Discord - Twitch API
