vercel dev not working

[kaushiksahu18]

I want to deploy my express app to vercel todoappdb
i have watched many videos and docs, and come up with idea to add vercel.json file showing blow

{
  "version": 2,
  "builds": [{ "src": "index.js", "use": "@vercel/node" }],
  "routes": [{ "src": "/(.*)", "dest": "/" }]
}

after this i did vercel login and then vercel dev, (source:vercel docs).
BUT ITS NOT WORKING
console log

$ vercel dev

I am also facing same issue

i was trying to deploy my express.js server, but now i think i only have one option, using server less i.g. cloudflare workers(provide free tiar), you can try too.
