Callback handler failed. CAUSE: [unenv] crypto.createCipheriv is not implemented!

I am encountering a problem when trying to deploy my Next.js app to :cloudflare: Workers after adding Auth0. I'm using:

- @opennextjs/cloudflare": "^0.3.3
- "@auth0/nextjs-auth0": "^3.5.0"

This is my route.ts file:

// app/api/auth/[auth0]/route.js
import { handleAuth } from '@auth0/nextjs-auth0/edge';

export const GET = handleAuth();

// app/api/auth/[auth0]/route.js
import { handleAuth } from '@auth0/nextjs-auth0/edge';

export const GET = handleAuth();

package.json scripts:

  "scripts": {
    "dev": "next dev --turbopack",
    "build": "next build",
    "start": "next start",
    "lint": "next lint",
    "build:worker": "opennextjs-cloudflare",
    "dev:worker": "wrangler dev --port 8771",
    "preview:worker": "npm run build:worker && npm run dev:worker",
    "deploy:worker": "npm run build:worker && wrangler deploy"
  },

  "scripts": {
    "dev": "next dev --turbopack",
    "build": "next build",
    "start": "next start",
    "lint": "next lint",
    "build:worker": "opennextjs-cloudflare",
    "dev:worker": "wrangler dev --port 8771",
    "preview:worker": "npm run build:worker && npm run dev:worker",
    "deploy:worker": "npm run build:worker && wrangler deploy"
  },

My build runs fine after

pnpm run preview:worker

pnpm run preview:worker

and I'm able to access the app locally at localhost:8771 ; however, when I try to access api/auth/login, I'm met with the following error:

[wrangler:inf] GET /api/auth/login 302 Found (449ms)
✘ [ERROR] Error [CallbackHandlerError]: Callback handler failed. CAUSE: [unenv] crypto.createCipheriv is not implemented yet!

[wrangler:inf] GET /api/auth/login 302 Found (449ms)
✘ [ERROR] Error [CallbackHandlerError]: Callback handler failed. CAUSE: [unenv] crypto.createCipheriv is not implemented yet!

When I run

pnpm run dev

pnpm run dev

on localhost:3000 everything is functioning -- I believe it's because I'm able to access the Node runtime, which has the crypto module.

I've found a similar issue here and cont'd here, where vicb mentions that

crypto.createCipheriv

crypto.createCipheriv

is not yet implemented by workerd.

I saw a post from Brett Willis in #workers-discussions mentioning that :cloudflare: Workers supports the Web Crypto APIs and the equivalents there are

crypto.subtle.encrypt()

crypto.subtle.encrypt()

and

crypto.subtle.decrypt()

crypto.subtle.decrypt()

.

I'm new to Next.js and Cloudflare, so if anyone can give me some recommendations on how to resolve this issue it would be greatly appreciated, thanks.
