I think netlify deploys are static- so that won’t work with NextJS previews. For NextJS previews you need a server. I haven’t tried myself but in this example it shows deploying to Vercel— have you tried that?

can you tell us real quick, wether this is an Vercel vs. Netlify issue or must be sth. else?

Okay, solved! The problem was with the build command.
I had
npm run build
, which was wrong.It needed to be
next build
Hope this helps somebody else! (Haven't tried on Netlify yet, but it's working for Vercel)
