SSR Auth with Tanstack Start requires hard refresh

I followed the Next.js guide for SSR Auth on https://appwrite.io/docs/tutorials/nextjs-ssr-auth/step-1

I tried to replicate it for Tanstack Start.

However, once setting the session, e.g. through the oauth callback, the getLoggedInUser returns null
A harde browser refresh is necessary in order to work.
I do not understand why this is happening or what I am doing wrong.

Here is the code: https://gist.github.com/Olgoetz/a685d61c130e87b8817cb780e46888a3

SSR Auth with Tanstack Start requires hard refresh

Try setting the sameSite to "lax" instead of "strict" and see if that solves that issue.

It used to happen to me too and the above mentioned solution helped.

Indeed, that fixed it.
How did you find this out?

A lot of paid agents did not suggest this xD

I was curious about what other options sameSite has and was trying them out and I got the solution just like that

Yes even paid agents were not recommending any solutions to me at first so I took the matters into my own hand.

The only valid argument I got from the agent, after I told it the solution I found myself,was when I try to go to my website via a link it blocks the cookies we saved if we use strict
lax solves 99% of the cookie issues.
