Vercel 127 Error deploying vercel application

I'm trying to deploy on vercel, before it was working fine until I added a map library called leaflet and now it's giving an error in the deploy.. I tried to run npm run build in the terminal but still an error.

PACKAGE.JSON

Solution

If you ever have any problems with building a npm project, it is always a good plan to try to re-install all packages.

The first step should always be to simply run npm i.

If this does not work, try to remove package-json.lock and delete .node_modules, before running npm i again.
