Returning in middleware

Hi, I'm just getting started with TanStack Start. Right now I'm trying to do something like: 
export const authMiddleware = createMiddleware({ type: 'function' }).server(async ({ next }) => {
  const h = getHeaders();

  if (h['x-auth'] !== 'good') {
    setResponseStatus(403);
    return json({ error: 'Forbidden' });
  }

  return next();
});
export const authMiddleware = createMiddleware({ type: 'function' }).server(async ({ next }) => {
  const h = getHeaders();

  if (h['x-auth'] !== 'good') {
    setResponseStatus(403);
    return json({ error: 'Forbidden' });
  }

  return next();
});
but this gives a type error and doesn't seem to work. How do I return in a middleware? Or should I be using something else for this?

I think with the middleware you have to return with next(). You will pass the json as part of the context. 
return next({
   context: {error: 'Forbidden'},
 })
return next({
   context: {error: 'Forbidden'},
 })
or with what you are trying to do. Throw an error instead 
throw new Error('Forbidden');
 
throw new Error('Forbidden');

you can also do 
throw json({error: "Forbidden"}, {status: 403})
throw json({error: "Forbidden"}, {status: 403})
