The Storage That Middleware Never Had

This middleware throws immediately on every incoming request.

REACT_MODULE // 0x42
import { NextResponse } from 'next/server';

export function middleware(request) {
  const theme = localStorage.getItem('theme');
  if (!theme) {
    return NextResponse.redirect(new URL('/onboarding', request.url));
  }
  return NextResponse.next();
}

What's the fundamental issue causing the crash?
