nextjs-server-side-error-debugging

To debug Next.js API routes, run the dev server, reproduce the error, and inspect the terminal logs for full stack traces. You can also wrap your API route handlers with try-catch patterns to surface clearer failure details.

Errors in getServerSideProps or getStaticProps are logged on the server, not the browser. Correlate the browser symptoms with the stack traces printed in your terminal during local development, or review hosting logs for production diagnostics.

The best way to get detailed Next.js server-side failures is to wrap your server-side code in getServerSideProps, getStaticProps, or API routes with try-catch patterns. This forces clearer error logging and provides actionable context from server logs.

To diagnose Next.js production server errors, you need to review your hosting logs. Production environments do not expose detailed stack traces to the browser, so checking the external hosting provider's logs is required for diagnostics.
