where to add custom parameters for Twitch as of V4?

[MatD1]

I need to add extra parameters into the provider so I am able to request my stream key from Twitch docs here.

I did go to the docs to attempt this however it sends me here which I don't think works in this version as when I tried to login it sends me to the error page http://localhost:3000/api/auth/signin?error=OAuthSignin and my console has an error error: message: "Cannot read property 'url' of undefined",

When I compare the code from here to the twitch provider in the nextauth node modules they are quite different.

How do I add extra parameters into the provider in v4?

This sounds very familiar to #2735 (comment) 😕

I am aware of the currently wrong link as well, but I'm not sure about the easiest fix: nextauthjs/docs#29

If you look for the v4 config: https://github.com/nextauthjs/next-auth/blob/beta/src/providers/twitch.ts

Interestingly enough, when I use next-auth/providers/twitch as is with:

Twitch({
  clientId: process.env.TWITCH_ID,
  clientSecret: process.env.TWITCH_SECRET
})

It signs me in correctly, with no errors. 🤷

Could you maybe give a reproduction to the issue?
