Error: The edge runtime does not support Node.js 'crypto' module

This error only come up after I added middleware Searched issue on GitHub , no report about it on better-auth (or I am blind) tried to search more info appears that next-auth also have same issue as better-auth I need help here: How to bypass it or we have to not use middleware until it fixes? My middleware.ts: 
import { NextRequest, NextResponse } from "next/server";
import { headers } from "next/headers";
import { auth } from "@/utils/auth";

export async function middleware(request: NextRequest) {
  const session = await auth.api.getSession({
    headers: await headers(),
  });
  if (!session) {
    return NextResponse.redirect(new URL("/", request.url));
  }
  return NextResponse.next();
}
export const config = {
  runtime: "nodejs", // I make sure this is nodejs
  matcher: ["/protected"], // Apply middleware to specific routes
};
import { NextRequest, NextResponse } from "next/server";
import { headers } from "next/headers";
import { auth } from "@/utils/auth";

export async function middleware(request: NextRequest) {
  const session = await auth.api.getSession({
    headers: await headers(),
  });
  if (!session) {
    return NextResponse.redirect(new URL("/", request.url));
  }
  return NextResponse.next();
}
export const config = {
  runtime: "nodejs", // I make sure this is nodejs
  matcher: ["/protected"], // Apply middleware to specific routes
};
What I did: 1. I create new next js app to try out better auth 2. I follow the installation guide here 3. I install mongo db adapter guide here 4. I copy and modify middleware.ts to work with my directory 5. bug ->This error occurs (the Image) The error: 
The edge runtime does not support Node.js 'crypto' module
The edge runtime does not support Node.js 'crypto' module
My attempt: I tried adding into config It seems like a next issue but I make a help request here Next-auth also have the sameissue: - Nextjs middleware edge runtime problem (with Mysql database with Knex package) After I try adding into config from next js docs: 
node:internal/process/promises:394
    triggerUncaughtException(err, true /* fromPromise */);
    ^
[CanaryOnlyError: The experimental feature "experimental.nodeMiddleware" can only be enabled when using the latest canary version of Next.js.]

You have to use an API request from your Middleware to the route handler.
