  Hi

  ! I don't think any kind of SSR will work for this, because this code won't run in the user's browser. It will run in the server, so the authentication cookies will not be present to be validated. Therefore, your code will always return a redirect to "/"

  I know in the app folder you can get the cookies off the request, and then you can make that same

  /me

  fetch with:

  
  
  

  // you will need to get cookies from req (Context?) and then look for the payload-token cookie
  
  fetch("http://localhost:8080/api/users/me", {
    headers: {
      Authorization: `JWT ${jwt from cookie on req}`,
    }
  }

  what

  @281120856527077378

  describes is the right pattern here. You just need to manually inject the token into the

  Authorization

  header within your server-side request. There's a demonstration of this in our official preview example, check it out

  https://github.com/payloadcms/payload/blob/master/examples/draft-preview/next-pages/src/pages/%5Bslug%5D.tsx#L74

  . It uses

  getStaticProps

  but the same principle applies.
