next/node app deployment errors with heroku

Question

I am trying to deploy the following web app with heroku:

https://github.com/darego1990/web1

although I get the following build log error and I am not sure why:

-----> Node.js app detected

-----> Creating runtime environment

   NPM_CONFIG_LOGLEVEL=error
   NODE_ENV=production
   NODE_MODULES_CACHE=true
   NODE_VERBOSE=false

-----> Installing binaries
   engines.node (package.json):  0.12.x
   engines.npm (package.json):   2.5.x

   Resolving node version 0.12.x...
   Downloading and installing node 0.12.18...
   Bootstrapping npm 2.5.x (replacing 2.15.11)...
   npm 2.5.x installed

Can you update your package.json file with below:

"engines": {
   "node": ">= 8.0.0"
}

It looks like your node engine is quite old and in next.js' github repo, looks like they are using >8.0.0.
