tRPC does not have headers data when refreshing.

I'm using tanstack-start, tRPC and better-auth in my project and have it setup like this
export async function createContext(opts: CreateNextContextOptions) {
  const session = await auth.api.getSession({ headers: opts.req.headers });

  return {
    db,
    session: session?.user || null,
    opts,
  };
}

const t = initTRPC.context<typeof createContext>().create({
  transformer: superjson,
});

export const createTRPCRouter = t.router;

I'm currently running into a problem where navigating normally in the app, I get the data that I need from tRPC. However, when reloading by CTRL+R I get UNAUTHORIZED since I'm using a protected procedure whichj looks like this:
export const protectedProcedure = t.procedure.use(({ ctx, next }) => {
  if (ctx.session === null || ctx.session?.id === undefined) {
    throw new TRPCError({ code: "UNAUTHORIZED" });
  }
  return next({
    ctx: {
      // infers the `session` as non-nullable
      session: { ...ctx.session },
    },
  });
});


So I investigated a little and have found that opts.req.headers just doesn't have the headers that I need. However, here's where I dont get it, the headers do absolutely exist.
I verified this by creating a server function
const logWebRequest = createServerFn().handler(async () => {
  console.log(
    "\n\n>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n",
    getWebRequest(),
    ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n\n",
  );
});

and using it on the loader like this before my trpc request
  loader: async ({ context, params }) => {
    await logWebRequest();
    await context.queryClient.ensureQueryData(
      context.trpc.vote.getAllVotes.queryOptions({ userId: params.me }),
    );
  }

But when I do console.log(opts.req.headers) inside createContext it does not exist.
