How to Fix the Vercel Rewrite Rules for Sanity

Hi, how do you fix the Vercel rewrite rules for Sanity? I lifted this line from their blog, but it doesn’t actually work:
"rewrites": [{ "source": "/(.*)", "destination": "/index.html" }]

this works for me in vercel.json

  "routes": [
    { "handle": "filesystem" },
    { "src": "/(.*)", "dest": "/index.html" }
or when hosting the sanity spa inside a next project I use this in next.config.js

async rewrites() {
  return [
    { source: "/cms", destination: "/cms/index.html" },
    { source: "/cms/:path*", destination: "/cms/index.html" },

Thanks, for some reason I can’t seem to get
to work either. I’m thinking maybe I’ll try wrapping it in a next app if the next few deploys don’t take.

Some thoughts: Is the sanity index.html there at all (the file is created with
sanity build
and in the right directory)? No conflicting routes (now.json / vercel.json, next.config)? Have you tried using the vercel cli locally?

Those are good ideas. After I came back with fresh eyes, I realized
"cleanUrls": true
was the culprit. Though I’m really not sure how that could get in the way of
. Anyway, thanks again for the help! 🙂
