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
};

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:

I create new next js app to try out better auth
I follow the installation guide here
I install mongo db adapter guide here
I copy and modify
```
middleware.ts
```
middleware.ts
```
middleware.ts
```
middleware.ts
to work with my directory

Next-auth also have the sameissue:

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