Answer 1

The command you are running is trying to scale up the number of worker processes to 1 but you have only declared a web process type. If you are trying to scale up the number of web processes you would use heroku ps:scale web=1. If you are trying to make a new worker process you need to define a worker in the procfile and push to Heroku before trying to scale it (worker: node server/worker.js). The Heroku documentation on process types should be of some help as well.
