I am encountering an issue with the Sanity visual editing tool in my Nuxt application hosted on Vercel. The error message displayed is:
PresentationTool-d136ce86.js:78 Unable to connect to visual editing. Make sure you've setup '@sanity/visual-editing' correctly

Nuxt configuration

sanity: {
    projectId: process.env.NUXT_ENV_SANITY_PROJECT_ID,
    dataset: process.env.NUXT_ENV_SANITY_DATASET,
    useCdn: true, // `false` if you want to ensure fresh data
    apiVersion: process.env.NUXT_SANITY_API_VERSION || '2024-03-15',
    // minimal: false,
    visualEditing: {

      // mode: 'live-visual-editing',
      stega: false,
      zIndex: 9999,
    },
  },

Reproduction

Steps to reproduce the behavior:

1. Set up a Nuxt application with Sanity integration.
2. Configure visual editing as per the Sanity Nuxt documentation.
3. Deploy the application to Vercel.
4. Attempt to use the visual editing tool (Presentation tool) in production.

What is expected?

The visual editing tool should connect and function correctly in the production environment, as it does in the local development environment.

What is actually happening?

Getting error message on production: Unable to connect to visual editing. Make sure you've setup '@sanity/visual-editing' correctly
