Has anyone passed supabase user to the tRPC context in Expo?

@react-native-async-storage/async-storage/lib/commonjs/AsyncStorage.js:63
    return createPromise(() => window.localStorage.getItem(key), callback);

ReferenceError: window is not defined

import { TRPCError, initTRPC } from "@trpc/server"

import { supabase } from "~/lib/supabase";

export async function createContext({ req }: FetchCreateContextFnOptions) {

  const {
    data: { user },
  } = await supabase.auth.getUser();

  return {
    user
  }
}

const t = initTRPC.context<typeof createContext>().create({
  errorFormatter({ shape }) {
    return shape
  },
})

export const createTRPCRouter = t.router
export const publicProcedure = t.procedure

const enforceUserIsAuthed = t.middleware( async ({ ctx, next }) => {

  if (!ctx.user) {
    throw new TRPCError({ code: "UNAUTHORIZED" });
  }

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

export const protectedProcedure = t.procedure.use(enforceUserIsAuthed);
