Hi @abhishekmadoliya-641, welcome to the Vercel Community!

What happens when you run `npm run build` and `vercel build` commands locally? Can you run both and share the outcome here?

If possible, please share your public repo or a [minimal reproducible example](https://vercel.com/guides/creating-a-minimal-reproducible-example). That will let us all work together from the same code to figure out what’s going wrong.

I see. Can you share the `package.json`, next config and vercel.json here?

My first suggestion would be to remove all `node_modules` and reinstall everything. Update the packages to their latest patch version and see if this fixes.
