SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Server-side errors in Next.js pages and API routes often don't surface clearly in the browser. Developers are left without actionable details and must rely on terminal or server logs to diagnose.

Core Features & Use Cases

  • Provides actionable guidance for locating and fixing server-side errors in getServerSideProps, getStaticProps, and API routes.
  • Helps identify where failures originate using terminal stack traces, logs, and instrumentation techniques.
  • Applicable to development workflows where consistent, repeatable debugging steps are needed.

Quick Start

Run the Next.js dev server and follow the terminal stack trace to identify and fix the server-side error.

FAQPage Schema
How do I debug Next.js server-side errors that only show in the terminal?

Debug Next.js server-side errors by running the dev server and reading the terminal stack trace. Locate the failing code in getServerSideProps, getStaticProps, or API routes, instrument the logic, and validate fixes through server logs.

Why does my Next.js API route show a generic error in the browser?

Next.js API routes show generic browser errors because the actual exception occurs server-side. You must inspect the terminal stack trace to find the origin line, instrument the route code with logging, and validate the corrected response via server logs.

What is the best way to find a stack trace for a getServerSideProps failure?

The best way to find a stack trace for a getServerSideProps failure is checking the terminal output during local development. The server logs surface the exact file and line number, allowing you to instrument the code and step through the logic to resolve the error.

How to fix getStaticProps errors when the browser provides no details?

Fix getStaticProps errors by locating the actionable stack trace in your terminal logs. Identify the failing data fetch or logic block, add instrumentation to catch the specific issue, and confirm the successful page generation by monitoring the server output.

Can I use terminal logs to debug Next.js API routes during development?

Yes, you can use terminal logs to debug Next.js API routes during development. Terminal logs provide actionable stack traces that reveal the exact server-side failure, enabling you to instrument the route and validate the corrected behavior without browser details.

What should I do when my Next.js server error stack trace is unclear?

When a Next.js server error stack trace is unclear, instrument your getServerSideProps, getStaticProps, or API route code with targeted logging. Run the dev server, reproduce the error, and use the new terminal output to pinpoint and fix the underlying server-side issue.
