I am following the **Add Login to Your Next.js Application** instructions, and get stuck at step **4: Add the dynamic Route Handler** as I keep getting the following error when testing `route.js`:

```auto
throw new TypeError(error.details[0].message);
              ^
TypeError: "secret" is required

```

Here is my directory structure:

- `project_root_directory/.env.local`
- `project_root_directory/src/pages/api/auth/[auth0]/route.js`)

I test it by adding:  
`console.log("the AUTH0_SECRET env var is set: ", !!process.env.AUTH0_SECRET);`

which always returns:  
`the AUTH0_SECRET env var is set: false`

Also, Next.js has two different routers: the `App Router` and the `Pages Router`, and we need to get this working with the `Pages Router`. Is there a tutorial on how to achieve these instructions with the `Pages Router`.

I would love some insights on what I am doing wrong.

[Instructions reference](https://auth0.com/docs/quickstart/webapp/nextjs/interactive)

Thank you!

Hi @startup,

Welcome to the Auth0 Community!

It seems that the error is indicating that you are missing a secret value. Please ensure that the secret value is set and located in the correct place.

Here is an example of configuring the Page Router, which you can reference:  
[Auth0 Next.js SDK - Page Router setup](https://github.com/auth0/nextjs-auth0?tab=readme-ov-file#page-router)

Let me know if you have any questions.

Thanks,  
Rueben

Hi @rueben.tiow ,

Thanks for the article! Long story short, it seems that the issue was actually the version of `'@auth0/nextjs-auth0'`.

Thanks for your help!
