If the error is, Error: MONGO_URL must be set in environment. Then it's evident that you haven't created your database for the app.
If the error is, Error: ROOT_URL must be set in environment. Then you'll need to set-up your root_url in the environment.

Been running into this problem but figured out. Hope this helps. :)
You need to remove .deploy.lock file if exists in your application folder
rm -rf /home/dokku/YOUR_APP_NAME/.deploy.lock
Check memory usage on the box. I’ve often seen it complain like that when its struggled to build the instance. Or try clearing the git repo on the server.
