Vercel doesn't show parts of the UI

Hey,
I have a problem with deploying my Nuxt application on Vercel: parts of the UI aren't shown. The first screenshot shows it, if I run

pnpm build

pnpm build

pnpm preview

pnpm preview

. The second screen shows the real result. I think the data is not even sent to the client.

I hope somebody can help me.
