Sanity client fetch error - has anyone encountered this before?

I'd be happy to help troubleshoot your sanity-client error! However, you didn't include the specific error message in your question. Since different errors have different solutions, let me cover the most common sanity-client issues:

Most Common sanity-client Errors:

1. Configuration Issues Make sure your client is properly configured:

import {createClient} from '@sanity/client'

const client = createClient({
  projectId: 'your-project-id',
  dataset: 'production',
  apiVersion: '2024-01-01', // Use current date
  useCdn: true, // `false` if you need fresh data
})

Missing or incorrect projectId, dataset, or apiVersion are the most common culprits.

2. CORS Errors If you see CORS errors in the browser console, you need to add your domain to allowed origins:

• Go to sanity.io/manage
• Select your project → API settings
• Add your domain (e.g., http://localhost:3000 for development)

3. Authentication Errors If you're writing data or accessing private content, you need a token:

const client = createClient({
  // ... other config
  token: process.env.SANITY_API_TOKEN,
})

4. Network/Fetch Errors

• Check your internet connection
• Verify the project ID and dataset combination is correct
• Ensure you're using the correct API URL format

5. GROQ Query Errors If the error happens during a query, check your GROQ syntax. The groq-js package can help validate queries locally.

To get more specific help, please share:

• The exact error message (including stack trace)
• Your client configuration code (remove any tokens)
• The code where the error occurs

This will help the community pinpoint the exact issue!
