No payload when using the nuxt-auth module

When using the nuxt auth module (https://auth.nuxtjs.org/) to preserve the preview stage, all payload.json are empty after static build.

After disabling the auth module everything works as expected.

@deepsoul Sorry, I wasn't able to reproduce your issue. Maybe if you have simple reproduction on codesandbox, I'll be able to investigate more.
