nextAuth v4 google oauth setup

[shawnlikescode]

I'm trying to do google oauth. This is what I get after selecting a google account. I'm using the v4 beta. Any ideas why I'm getting this? Everything else appears to be right. Am I missing new specific something in v4

Yes. Try reading the migration docs:

https://next-auth.js.org/getting-started/upgrade-v4#adapters

This has been asked already twice today:
https://github.com/nextauthjs/adapters/issues/208
https://github.com/nextauthjs/adapters/issues/209

Update
Four times in total.
https://github.com/nextauthjs/adapters/issues/211

Assuming you read the docs, I am happy to take suggestions, how to elevate the relevant part at this point, because we seem to fail to communicate that correctly.

Thanks! Yeah. Read the docs but I just missed that note about flagging the adapter as @next.

I would maybe suggest adding the same v4 note to the errors page:
https://next-auth.js.org/errors

If someone else is like me, they'll look here first. It would be a lot harder to miss it on this page if they miss it on the adapter page.

I'll discuss it, thanks.

Generally it's not an error people are expected to get with correct usage, while the error page documents known errors thrown by NextAuth.js on purpose.

It is a suggestion nonetheless so we will evaluate it.
