heroku deploy error build script 'better-npm-run build'

seems adding a version fix into package.json does not really work, "engines": { "node": "6.9.x" }

note: Error above is when without a engines set, but even when I did push the new code above up, and the error still persist. Thought?

and this error when I ran with 6.9.x

Note: also, that, I do not think set prod to false is a fix, as it will start deploying develop version of the app into production. its more like workaround. No? Correct me if I am wrong~
