state-mismatch for my oauth proxy

Next.js

I'm trying to build a nextJS app with betterAuth.

There is just a problem I'm facing- I'm having multiple urls- for testing, dev, etc, and only one Google OAuth Client and only one Github Client. So I'm using my proxy which just redirects the urls, like ventry.DOMAIN.de or pr-123-ventry.DOMAIN.de or dev-ventry.DOMAIN.de

But I'm getting a state mismatch error and I can't figure out how to solve the problem.

Do I even need my proxy? Is there a better way to solve this?

Here's a flow:

POST 200 /api/auth/callback/github

GET 302 https://github.com/login/oauth/authorize?redirect_url
https://auth-ventry.DOMAIN.de/api/auth/callback/github

GET 302 https://auth-ventry.DOMAIN.de/api/auth/callback/github?code=xxx

GET 302 https://auth-ventry.DOMAIN.de/api/auth/callback/github

GET 200 https://ventry.DOMAIN.de/api/auth/error?state=state_not_found

So I don't know what I'm missing. I've tried multiple things like changing the baseUrl- etc.

Here's the repository: https://github.com/MarkusLoeffler01/Ventry/tree/19-add-docker-and-cicd-and-introduce-new-dev-branch

And my proxy: https://github.com/markusloeffler01/ventry-proxy
