tRPC SSG Helper w/ new Clerk middleware

So my goal is to do almost exactly what Theo does in his tutorial using the SSG helper for profile pages, but due to updated Clerk middleware I had to change my trpc.ts file. I have my trpc.ts file set up identical to this: https://github.com/perkinsjr/t3-app-clerk-minimal/blob/main/src/server/api/trpc.ts There is a comment in there that says:

/**
 * This helper generates the "internals" for a tRPC context. If you need to use
 * it, you can export it from here
 *
 * Examples of things you may need it for:
 * - testing, so we dont have to mock Next.js' req/res
 * - trpc's `createSSGHelpers` where we don't have req/res
 * @see https://create.t3.gg/en/usage/trpc#-servertrpccontextts
 */

But I can't figure out how to use the "auth" object in the context when defining the SSG helper, it's always erroring when I try to set it up:

import { createServerSideHelpers } from "@trpc/react-query/server";
import { appRouter } from "~/server/api/root";
import { prisma } from "~/server/db";
import superjson from "superjson";


export const generateSSGHelper = () =>
  createServerSideHelpers({
    router: appRouter,
    ctx: { auth, prisma }, // auth errors here saying: No value exists in scope for the shorthand property 'auth'. Either declare one or provide an initializer.ts(18004)
    transformer: superjson,
  });

import { createServerSideHelpers } from "@trpc/react-query/server";
import { appRouter } from "~/server/api/root";
import { prisma } from "~/server/db";
import superjson from "superjson";


export const generateSSGHelper = () =>
  createServerSideHelpers({
    router: appRouter,
    ctx: { auth, prisma }, // auth errors here saying: No value exists in scope for the shorthand property 'auth'. Either declare one or provide an initializer.ts(18004)
    transformer: superjson,
  });

have you tried not passing anything in place of auth because in nextauth version of SSGHelper works with session=null

Tried this, no luck because auth is required in ctx
