Description

I am experimenting with the v2 beta on Next.js 13. I added middleware to my project following the examples in #815, and the server raises an error trying to read the request cookies:

at MiddlewareCookies.getAll (webpack-internal:///(middleware)/./node_modules/@auth0/nextjs-auth0/dist/utils/middleware-cookies.js:18:39)
    at CookieStore.eval (webpack-internal:///(middleware)/./node_modules/@auth0/nextjs-auth0/dist/auth0-session/cookie-store.js:128:54)

    at SessionCache.eval (webpack-internal:///(middleware)/./node_modules/@auth0/nextjs-auth0/dist/session/cache.js:20:63)

I understand this is all very new. Thanks for your work on implementing middleware support!

Reproduction

1. Configure Auth0 (e.g. using the sample app)
2. Install next@13.0.1
3. Add a middleware.ts to the project:

   import { withMiddlewareAuthRequired } from "@auth0/nextjs-auth0/middleware";
   
   export default withMiddlewareAuthRequired();

4. Run the server and load a page in the browser

Thanks for raising @wjrogers

This looks like it's caused by a breaking change in next@13.0.1 from vercel/next.js#41526

You should be able to use next@13.0.0 while we investigate
