I am experiencing the same exception. Please find the corresponding stack trace below:

It's #251 I gotta migrate off of v5 API and to give warnings Twitch does "blackouts" of APIs they're going to soon deprecate. Today the blackout window was an hour.

https://discuss.dev.twitch.tv/t/legacy-twitch-api-v5-i-e-kraken-shutdown-reminder-february-28-2022/36589

I'll try and migrate to just using GQL sometime today.

[IncorrigiblyBelligerent]

The v5 API is up now, for the time being

I'm curious as to whether you'll be able to migrate, as Twitch seems specifically uninterested in providing a VOD chat api now.

I do not think they will ever provide an official API for chat comments. I mean I've always just used their undocumented API and will just keep doing so. I just needed to migrate some requests about getting VOD/Clip info off of kraken.

~1.40.5~ ~1.40.6~ 1.40.7 doesn't use the Kraken API anymore, so next blackout this version should work. If there are no bug reports for a few days I'll mark it as stable and let people auto update to it.

I moved to GQL instead of Helix because I didn't want people to have to log in, or use some kind of server in my control to proxy requests. Interestingly it looks like TwitchLeecher went the helix approach and now makes users log in, strange. Anyways give it a shot if the regular version isn't working.

Today it started happening again, for any videoId I tried:

Actually tried with 1.40.7 release and got this instead:

[mohad12211]

@glubsy 1.40.7 working with no issues here, did you try to reboot/delete the temp directory?

[glubsy]

@mohad12211 indeed, it works now. Might have been a temporary issue on Twitch's side.

However, I still get the "Object reference not set to an instance of an object" error instead of a proper 404 error when trying to download --id 1290915475 which is a deleted video so I'm expecting a 404 error (not a big deal I can live with that).
