Hello, I'm having the same problem.

When I run next dev command and fetch some data with sanity using client.fetch(query) I get GET /_next/static/webpack/app/(root)/server-actions.js.map 404 in 333ms at the console.

The only way to avoid getting this problem is by commenting the fetch so I think it's something related with that.

My versions are:

• "sanity": "3.66.1",
• "@sanity/vision": "3.66.1",
• "@sanity/image-url": "1.1.0",
• "sanity-plugin-markdown": "5.0.0",
• "next-sanity": "9.8.3-canary.1",
• "next": "15.0.3",

NPM and Node versions:

• npm 10.9.0
• Node 22.11.0
