What version is this on? The stand alone disco executable was deprecated as of version 3.0.0 and the CLI syntax now works like:
php public/index.php db-restore 'app/db/' 'YOUR_STRUCTURE_FILE'
See http://discophp.com/docs/command-line-interface for more information on the CLI.

It appears your using a project wrapper that was for versions pre 3.0.0 and a version of the framework that is 3.0.0 or later. You're using at least using version 3.0.2 as this is when exceptions starting being thrown when accessing config keys that don't exist.
