What's your tsconfig? Do you have something regarding declaration enabled? I think I had similar issues with declaration or declarationMap enabled...

i'll try upgrading soon to the newest rc anyways. because of #Can I use the "Streaming with Server Components" strategy with tRPC? seems to be working.

something maybe offtopic: the trpc example now produces a hydration error because of toLocaleString on my machine. which makes sense, since the browser has a different locale configured. not sure if that's intended for such an example

I mean that there's an additional fetch request in the network tab.

Huh, interestingly, it still doesn't work with rc.441 (same code as before) However, as soon as the page is exported as an async function (export default function Home vs export default async function Home) it works. This happens in dev and prod mode.

How do I use the rsc-rq-prefetch example with a protected procedure?
What version of tanstack react-query do you use? Maybe that's the issue and not trpc itself... Since, I don't think trpc is deciding if it should run during SSR or not... If you do something like this 
headers: {
    'x-trpc-source':
       typeof window !== 'undefined' ? 'react-query' : 'react-query-ssr',
    },
headers: {
    'x-trpc-source':
       typeof window !== 'undefined' ? 'react-query' : 'react-query-ssr',
    },
in the httpBatchStream, and also log the headers in the protected procedure middleware - does it get logged? Because I think my setup is wrongfully calling the useSuspense query on the server during SSR and, since the server during rendering is somehow not authed, it fails...

Hi Julius I've tried this and updated the TanStack query library. However, I'm still experiencing the same behaviour. The repro based on today's state of the trpc app dir example is here: https://github.com/michaelschufi/trpc-next-app-dir-2 The significant changes I made: https://github.com/michaelschufi/trpc-next-app-dir-2/commit/f7de44043d686b7fffad68ae23011edcc4fb1205

How do I use the rsc-rq-prefetch example with a protected procedure?
So what I would expect is: The trpc handler should be hit 1-2 times instead of 3 times. - Once for the void trpc.foo.prefetch(); in page.tsx ('x-trpc-source': 'rsc') - Maybe once for the trpc.foo.useSuspenseQuery(); in foo.tsx ('x-trpc-source': 'react-query') in case the server prefetch failed. But it should never be called during SSR with the trpc client component in rcc.tsx ('x-trpc-source': 'react-query-ssr'). Are those assumptions correct?

Hmm, does your trpc client component client run during SSR? I'm experiencing strange behaviour... My next.js receives 3 trpc requests for the following page: foo/page.tsx 
import { HydrateClient, trpc } from '@/app/api/trpc/client/rsc';
import { Foo } from '../../foo';

const FooPage = async () => {
  void trpc.foo.prefetch();

  return (
    <HydrateClient>
      <Foo />
    </HydrateClient>
  );
};

export default FooPage;
import { HydrateClient, trpc } from '@/app/api/trpc/client/rsc';
import { Foo } from '../../foo';

const FooPage = async () => {
  void trpc.foo.prefetch();

  return (
    <HydrateClient>
      <Foo />
    </HydrateClient>
  );
};

export default FooPage;

Hi @testsubject1137 Have you had some success with more recent versions in the meantime? Even with rc.403, I'm getting an error in my isAuthed trpc middleware. 
const isAuthed = t.middleware(({ next, ctx }) => {
  if (!ctx.auth.userId) {
    throw new TRPCError({ code: 'UNAUTHORIZED', message: 'Not authenticated' });
  }

  return next({
    ctx: {
      auth: ctx.auth,
    },
  });
});
const isAuthed = t.middleware(({ next, ctx }) => {
  if (!ctx.auth.userId) {
    throw new TRPCError({ code: 'UNAUTHORIZED', message: 'Not authenticated' });
  }

  return next({
    ctx: {
      auth: ctx.auth,
    },
  });
});
since, as you've said, the server is running the client component query during ssr.

Thanks for looking into it. 🙏 Hmm, data transorming is kind of really useful. I don't think there's a workaround, correct?
