Fixing client-side exceptions in Next.js v0 projects after deployment

Hi everyone

I’m running into an issue with a project built using Vassel v0. The app works fine during development, but after publishing, it fails to load both in the live deployment and in the VNode preview.

Right after logging in, the app crashes and shows this error:

Application error: a client-side exception has occurred while loading v0-livestock-import-export-analysis.vercel.app (see the browser console for more information).

Here’s the deployed link:

https://v0-livestock-import-export-analysis.vercel.app/dashboard

This only happens after publish — it doesn’t occur during development. The dashboard never renders once the error appears.

Has anyone experienced something similar with v0/VNode after deployment? Any pointers on common causes (env vars, auth, client-only code, or build config) would be really appreciated.

In general, to debug this type of error, you should check your browser console for error logs, and then you can copy & paste those to v0 (explaining to it what you did and what the problem is), then ask v0 to fix the issue. In most browsers, you can access the browser console by pressing CTRL/CMD + SHIFT + I, then selecting “Console” from the tabs at the top of the developer panel.

Unfortunately, I don't have access to the dashboard on your website or I would do this for you

First thing I'd check is the browser console, like recommended.

You can also check the runtime logs on the Vercel dashboard if the browser console doesn't have the info you need
