Answer 1

Specify the version of node The version of Node.js that will be used to run your application on Heroku, should also be defined in your package.json file. You should always specify a Node.js version that matches the runtime you’re developing and testing with. To find your version type node --version.

Your package.json file will look something like this:

"engines": { "node": "10.x" },

It should work
