enablePrerenderSourceMaps

The enablePrerenderSourceMaps option lets Node.js use existing source maps during the prerender phase of next build. When source maps are available, error stack traces point to the original source code. It defaults to true.

This option does not generate source maps. Webpack does not generate server source maps by default. To generate them when investigating prerender errors, use next build --debug-prerender.

To disable it, set enablePrerenderSourceMaps to false:

import type { NextConfig } from 'next'
 
const nextConfig: NextConfig = {
  enablePrerenderSourceMaps: false,
}
 
export default nextConfig

Reference

Disabling source maps during prerendering can reduce build memory usage, but makes prerendering errors harder to debug.
