Hello,

I am not sure what you are trying to do. It appears that you are deploying Next.js application? By default, you don't need a vercel.json to deploy Next.js app unless you need a custom config.

if i did not add vercel.json that. error Error: Cross-reference between Middleware and Edge

Hi Vikash,

Have you tried our Next.js starter template? https://vercel.com/templates/next.js This should give you brief about deploying a fresh Next.js application

Now I fixed that error .
