Why does my Create-React-App on Heroku have NODE_ENV=development?

Question

I want to use NODE_ENV in my Create-React-App as described in https://medium.com/@tacomanator/environments-with-create-react-app-7b645312c09d

But when I run it on Heroku, process.env reports { NODE_ENV: "development", PUBLIC_URL: "" } - why? NODE_ENV is production in my Heroku dashboard.

I solved it myself with the create-react-app-buildpack buildpack:

heroku buildpacks:add https://github.com/mars/create-react-app-buildpack.git

And then redeployed my app to Heroku.
