Build directory not writeable
Why This Error Occurred
The filesystem does not allow writing to the specified directory. A common cause for this error is starting a custom server in development mode on a production server, for example, Vercel which doesn't allow you to write to the filesystem after your app is built.
Possible Ways to Fix It
When using a custom server with a server file, for example called server.js, make sure you update the scripts key in package.json to:
{
"scripts": {
"dev": "node server.js",
"build": "next build",
"start": "NODE_ENV=production node server.js"
}
}
and the custom server starts Next in production mode when NODE_ENV is production
const dev = process.env.NODE_ENV !== 'production'
const app = next({ dev })
