vercel-builder: Error deploying Nuxt.js application

Hello,

I’m trying to deploy a new Nuxt.js (v2.15.0) SSR application into Vercel, however I’m getting a lot of errors. I tried a few things that I saw in #369 , #425 which is basically set a fixed version at "@nuxtjs/vercel-builder", however none of then worked, I get the same errors everytime.
