Describe the bug

I'm using nuxt-auth for JWT authentication with my own backend. I wanted to create a middleware, which adds the accessToken to every request.

As seen in the reproduction, i followed exactly the guide here https://auth.sidebase.io/guide/authjs/server-side/jwt-access#jwt-access but i get the error:

 WARN  "next-auth/core" is imported by "node_modules/@sidebase/nuxt-auth/dist/runtime/server/services/authjs/nuxtAuthHandler.mjs", but could not be resolved – treating it as an external dependency.                                                                     09:49:24

Hi @FabianClemenz 👋

Please ensure you are using next-auth@4.21.1 or earlier. In the subsequent version, they made a breaking change, where they did not expose the core anymore!

You can see more on this in our docs: https://auth.sidebase.io/guide/authjs/quick-start

Hi @zoey-kaiser

i'm not using the AuthJS Provider but the refresh provider. Do i also need to install it?

i'm not using the AuthJS Provider but the refresh provider. Do i also need to install it?

The server-side functions are currently only supported by the authjs provider, which is why it prompts you to install the package. The local provider only supports client-side fetching. We have an open PR at the moment, which adds support for server-side token and session fetching for the local provider (#855)

Until it is released, you can fetch the Token manually on the server-side using:

Get Token:

export default defineEventHandler(() => {
  const rawToken = getCookie(event, 'auth.Token') // Or you custom cookie name
  const formattedToken = `Bearer ${rawToken}`
})

If this works for you! I would close this Issue, feel free to comment in #854 where we previously discussed server-side access for the local provider 🤗
