Title: Issue with setTokenManager Server Middleware Not Working Properly in Vercel Deployment

Description:

Environment:

• Framework & Version: Nuxt.js "^3.7.1"
• Deployment Platform: Vercel
• Node.js Version: v20.9.0
• Relevant Packages/Libraries:
  {
  "name": "nuxt-app",
  "private": true,
  "scripts": {
  "build": "nuxt build",
  "dev": "nuxt dev",
  "generate": "nuxt generate",
  "preview": "nuxt preview",
  "postinstall": "nuxt prepare"
  },
  "devDependencies": {

  "@sidebase/nuxt-auth": "^0.6.0-rc.0",

  },

  },
  "overrides": {
  "vue": "latest"
  }
  }

Problem:
I have deployed my Nuxt.js project on Vercel and am encountering an issue with my setTokenManager server middleware, which is not functioning as expected. In my local environment, everything works fine, but in the Vercel deployment, the token is returned as null.

Code Snippet:

import { getToken } from '#auth'

export default defineEventHandler(async (event) => {
    console.log(event, "event")

    let token = await getToken({ event })
    console.log(token, "here")
    setCookie(event, 'token', token?.jwt, { httpOnly: true })
});

Issue Details:

• The getToken function, when invoked, doesn't retrieve the expected token. Instead, it returns null.
• This issue is only observed after deployment on Vercel. Locally, the function works as intended.
• I have already ensured that the environment variables are correctly set up in Vercel.
• The middleware seems to be getting executed, as logs within the function show the expected output for the event.

Troubleshooting Done:

• Checked and verified all environment variables on Vercel.
• Reviewed middleware configuration for any discrepancies between local and production environments.
• Ensured that there is no issue with cookie handling in the setCookie function.

Additional Context:
Here is the console output of the event object:

I am at a loss for what might be causing this issue and would appreciate any guidance or suggestions on how to resolve it. Has anyone else faced a similar issue, or does anyone have insights on what might be going wrong here?

Thank you in advance for your assistance!
