Last updated: Jan 16, 2025
Hi, I’m hoping I can get on a call with someone who can help me resolve this issue I seem to have between Vercel and Sanity.io
I’ve realistically been stuck on this issue for over a week. Many attempts on my own until I reached out for help last week. Please advise. Thank you.
AI Update

I completely understand your frustration—being stuck for over a week on an integration issue is really tough! While Sanity doesn't offer scheduled support calls as a standard service, you have several excellent options to get help:

Immediate Community Help

Your best bet for quick assistance is the Sanity Discord community. The community is very active with helpful developers and Sanity team members who can troubleshoot Vercel integration issues in real-time. Sanity recently moved from Slack to Discord, so this is where all the action happens now.

Common Vercel + Sanity Issues

Since you mentioned issues between Vercel and Sanity, here are the most common culprits:

  • CORS errors: Usually resolved by configuring allowed origins in your Sanity project settings (under API settings in your project dashboard)
  • Environment variables: Make sure your NEXT_PUBLIC_SANITY_PROJECT_ID, NEXT_PUBLIC_SANITY_DATASET, and any API tokens are properly set in Vercel's environment variable settings
  • Preview/Draft mode: Issues with next-sanity preview configuration or perspective settings
  • ISR/revalidation: Webhook configuration for triggering rebuilds when content changes (though consider Sanity Functions as the modern alternative)
  • API version: Recent breaking changes in API v2025-02-19 changed the default perspective to published instead of raw

When you post in Discord, include your specific error messages, relevant code snippets, and what you've already tried—this helps the community diagnose faster.

Professional Support Options

If you need dedicated help:

  • Sanity Agency Partners: Browse Sanity's agency partner directory to find consultants and agencies who specialize in Sanity + Vercel integrations and can provide paid consulting
  • Vercel Experts: Similarly, Vercel has an experts directory if the issue is more deployment-focused
  • Enterprise Support: If you're on a Growth or Enterprise plan, you may have access to direct support channels through your Sanity dashboard

Documentation Resources

Make sure you've checked the Sanity docs for Next.js integration guides and Vercel's deployment documentation—they cover most integration patterns and common issues.

Don't give up! The Discord community is genuinely helpful, and someone has likely solved your exact issue before. Post there with details and you should get responses within hours, not days. Good luck!

Does building locally work?
Yes
try 
vercel build
and then 
vercel deploy --prebuilt
user A
thanks for the suggestion. I was able to replicate the issue using 
vercel build
and received the same error as when it deploys to github. Would you have any other suggestions?
The API version string exists, as the thread beforehand suggests, but Vercel is not recognizing the hard code API string.
Could you paste your sitemap.xml and client config?
Your comment made me re-evaluate the route for 
/studio
on the sitemap, only to find that it was not updated properly. This route update fixed the disconnect between Vercel and Sanity -- I’m experiencing a different error now that has nothing to do with this particular issue anymore. Thank you so much!!
Great! Let me know if I can help with your other errors
I appreciate it. Thank you so much, have a wonderful weekend!
