Deployment fails on Heroku

Hi Guys,

I have created a small app and want to deploy and test it on server. I choose heroku (for staging as it’s deployment is free) for deployment and used this [Medium ] blog.(How to Run a Meteor.js Application on Heroku in 10 Steps | by Leonardy Kristianto | Medium)

I encouter this issue while deploying on Heroku. Please help

I’d check put that build packs detection url it’s telling you to visit.
