getServerSideProps withUserTokenSSR returns user null in staging environnement but works in local

[Felixaverlant]

Hey there,

I wanted to add SSR to my project with getServerSideProps using the new withUserTokenSSR.
Version used: ^1.0.0-canary.18
In dev env everything works just fine.
In staging the user returned by withUserTokenSSR is null.

This code sample works on one page in local :

export const getServerSideProps = withUserTokenSSR({})(async ({ req, res, user }) => {
 console.log(user)
}
export default withUser()(MyPage)

But it does not work on a staging environnement and get a null user.

If I had

whenUnauthed: AuthAction.REDIRECT_TO_LOGIN,

I obviously get an infinite loop between my login page and the other page (in staging env only).

I'm using a custom (but almost identical as the default) tokenChangedHandler.
authUser return null in staging env.

Do you have any idea where I should look at?

Thanks.
