Using the plugin with no config.json #14

EDIT: Submitted by mistake before writing a message.

I'm using NodeBB on Heroku and I need S3 for all the file uploads. I installed the plugin using npm and then pushed the directory back up to Heroku. I'm configuring everything as environment variables, so access key, secret key, host and bucket are all defined in the Heroku control panel. As I understand, path would be set by default to /.

At the moment I'm getting two errors, one on the console:

warn: [plugins/nodebb-plugin-s3-uploads-updated] Mapped path 's3 => /app/node_modules/nodebb-plugin-s3-uploads-updated/public' not found.

And one on the admin control panel:

Internal error.
Oops! Looks like something went wrong!
/api/admin/plugins/s3-uploads
Cannot find module './../../config.json'

This second one might be the issue here, as I have no config.json on the server. All variables for NodeBB configuration are also defined as environment variables.
