Description

After installing the v3 beta in an fresh nextjs app and setting up the api handlers I'm consistently receiving a 500 HTTP Error when visiting any of the handler routes (e.g. /api/auth/login). App only has app router routes, no pages directory. Not using any middleware either.

Nothing is getting logged to the console either. So it's hard to debug.

Seems I'm not the only one. Same error reported here and here.

Reproduction

1. I started a new fresh nextjs app with all the defaults (app router checked)
2. Installed the beta npm i @auth0/nextjs-auth0@beta
3. Added env vars for my Regular Web Application to .env.local
4. Set up the auth0 api handler route under app/api/auth/[auth0]/route.ts
5. Added the UserProvider in the root layout
6. Add the client component sample from the read me to page.tsx
7. Start the app and go to http://localhost:3000/api/auth/login and saw the error above

Thanks for sharing those steps @jalvarado91

This is also failing for me with Node 16 (it's working with Node 18)

I'll investigate and get back to you

ok, I understand the issue and will work on a fix. In the meantime, you can use the Beta with Node 18 & 20
