SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you debug Next.js failures that do not show useful details in the browser, especially when server-rendered pages, API routes, or refresh-only errors fail silently.

Core Features & Use Cases

  • Server-side error diagnosis: Directs you to the terminal or hosting logs where the real stack trace appears.
  • Targeted debugging workflow: Recommends try-catch wrappers and explicit logging to expose the true failure point.
  • Common Next.js scenarios: Useful for getServerSideProps, getStaticProps, API routes, production-only issues, and refresh-time failures.
  • Use Case: A page returns a generic 500 error after refresh, but the browser console is empty; this Skill helps you locate the actual error in server output and narrow down the cause.

Quick Start

Inspect the terminal running your Next.js server for the real error message, then add temporary server-side logging around the failing code if needed.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
Why does my Next.js page return a 500 error but the browser console is empty?

Next.js server-side errors often fail silently in the browser. The actual stack trace appears in the terminal running your dev server or in your hosting platform logs, not the browser console.

How do I debug errors in Next.js getServerSideProps or API routes?

To debug getServerSideProps and API routes, inspect the terminal output for the real error message and add temporary try-catch wrappers with explicit logging around the failing code to surface the stack trace.

Where can I find the actual stack trace for a silent Next.js server-side failure?

For silent Next.js server-side failures, check the terminal output where your Next.js server is running or review your production hosting logs to locate the actual stack trace.

What's the best way to catch hidden errors in Next.js getStaticProps during refresh?

The best way to catch refresh-only failures in getStaticProps is adding explicit try-catch error handling blocks to surface the true failure point and reviewing the terminal logs.

Can I use try-catch blocks to expose Next.js production-only server errors?

Yes, adding explicit try-catch wrappers around server-side code in getServerSideProps or API routes helps expose the true failure point and surfaces stack traces in production hosting logs.

How do I add server-side logging to diagnose Next.js API route failures?

Add temporary server-side logging inside your API routes and getServerSideProps functions to expose the true failure point, then check the terminal output to narrow down the cause.
