I run into problems installing the bundle mentioned in the update. Checked all similar questions, but don’t see any output like mine - “missing required flag”?
Edit: Looks like I need to name the app, but when I try to do that, I get the same message again.
UPDATE 2019-01-04: If you run into an error on the next command stating that you need to use Bundler 2 or greater with this lockfile, you’ll need to run:
heroku buildpacks:set https://github.com/bundler/heroku-buildpack-bundler2
