I'm getting an error (on Sinatra + ActiveRecord Heroku) that Database configuration does not specify adapter.
From some research, it looks like this is because Heroku expects there to be no environmental variables used during rackup.
I removed the env vars from the db environments file that listed the database URL, but I'm still getting the same error.
EDIT: This also worked just a day ago with the db files unchanged, so I'm not sure what could be wrong.
