nextjs - 💡(How to fix) Fix Turbopack Build Error Could not parse module. [project]/node_modules/next/dist/server/route-modules/app-route/vendored/contexts/router-context.js [1 comments, 2 participants]

I am using nx monorepo to setup 3 nextjs apps. my development server build (nx run app:build:development) with turbopack working fine but nx run app:build:production giving error when collecting data on prerender. Collecting page data using 11 workers ...Error: Could not parse module '[project]/node_modules/next/dist/server/route-modules/app-route/vendored/contexts/router-context.js', file not found

TL;DR

The issue can likely be resolved by adjusting the Next.js configuration to properly handle the prerendering process with Turbopack.

Guidance

• Verify that the next.config.js file is correctly configured for Turbopack and prerendering.
• Check the experimental section in next.config.js to ensure that turbo is enabled and properly configured.
• Review the getStaticProps functions in your pages to ensure they are correctly implemented and not causing issues during prerendering.
• Consider setting concurrentWorkers to a lower value in next.config.js to reduce the load on the system during prerendering.

Example

No specific code example can be provided without more details on the next.config.js file, but ensuring the experimental section is correctly set up is crucial:

module.exports = {
  //... other configurations
  experimental: {
    // Ensure turbo is enabled
    turbo: true,
  },
}

Notes

The exact solution may depend on the specifics of the next.config.js file and the implementation of getStaticProps in the application. The provided NX Report and environment details suggest that the issue might be related to the configuration or the version of Next.js and its dependencies.

Recommendation

Apply a workaround by adjusting the next.config.js file to properly handle prerendering with Turbopack, as upgrading to a different version of Next.js or its dependencies might not be feasible or necessary based on the provided information.
