It looks like your workbench can't find its database.yml file. This file is
included in the arvados-workbench package at

  /var/www/arvados-workbench/current/config/database.yml

The database.yml file just points to 'nulldb', because workbench doesn't have
its own database, as you said.

Can you see if that file exists on your system? Is the arvados-workbench
package fully installed?

Thanks,
Ward.
