Is there a way to disable stack trace in development?

Does anyone know how to see the error page instead of the stacktrace in dev?

According to the documentation, it will show the proper error page in production: https://nextjs.org/docs/advanced-features/custom-error-page#customizing-the-error-page

Is there a flag to see the error pages in dev?

If you run next build && next start this will emulate production instead of next dev.

Thanks for the tip! Does it mean I have to restart the server every time I make a change ? i.e. losing hot module reload

Yes. I haven't tried this, but maybe setting NODE_ENV=production will work. I'm not sure the full criteria for showing that page.

If I'm looking at the code correctly, it looks like it's hardcoded when starting dev server so I guess there's no flag atm to do this :(

Would be great to have a flag - this would be most useful when we're trying to build custom error pages & corresponding logic!

next build && next start on large projects could be fairly slow for development 😅
