How do I troubleshoot my Next.js deployment issues?

I'm having trouble deploying my Next.js app. It keeps throwing errors. What should I do?

First, can you share the specific error messages you're encountering? That will help me assist you better.

I'm getting a 404 error after deployment, but it works fine locally.

A 404 error often indicates that the routing isn't set up correctly. Have you checked your next.config.js for any custom routes?

Yes, I have some custom routes. Should I adjust them?

Yes, ensure that your custom routes are correctly defined and that they match the paths you're trying to access. Also, check your deployment platform's settings.

Thanks! I'll look into that. What else should I check if the issue persists?

If the issue persists, check your build logs for any warnings or errors, and ensure that your environment variables are correctly set.
