TRPC Server error handling?

So I've been refactoring my old project with T3 +app router that @julius recently added to T3 stack and I was just fiddling around trpc and its context I stumbled upon a problem.

I have a trpc middleware that checks for authed user

enforceUserIsAuthed

enforceUserIsAuthed

const enforceUserIsAuthed = t.middleware(({ ctx, next }) => {
  if (!ctx.sessionIdToken) {
    throw new TRPCError({ code: 'UNAUTHORIZED' });
  }

  return next({
    ctx: {
       ...
    },
  });
});

const enforceUserIsAuthed = t.middleware(({ ctx, next }) => {
  if (!ctx.sessionIdToken) {
    throw new TRPCError({ code: 'UNAUTHORIZED' });
  }

  return next({
    ctx: {
       ...
    },
  });
});

And there is a problem. When I use the client trpc calls (react) I have a

onError

onError

props for queryclient that I can check for that error and react (especially for 401 and redirect). But when it throws in the RSC this triggers error boundaries and throws uncaught TRPCClienterror.
How am I supposed to handle server errors in this case?

createTRPCProxyClient

createTRPCProxyClient

doesnt seem to have any onerror handler.
