Summary:

Steps to reproduce:

Expected behavior:

error free run of db:load_notifications

Actual behavior:

RAILS_ENV=production bundle exec rake db:load_notifications rake aborted! Psych::AliasesNotEnabled: Alias parsing was not enabled. To enable it, pass aliases: true to Psych::load or Psych::safe_load.
