Unable to seed cycle analytics data

Summary

SEED_CYCLE_ANALYTICS=true bundle exec rake db:seed_fu FILTER=cycle_analytics

The seeding script above breaks with the following error;

NoMethodError: undefined method `success!' for nil:NilClass
(eval):210:in `block in deploy_to_production'
(eval):203:in `each'
(eval):203:in `deploy_to_production'
(eval):99:in `block (2 levels) in seed!'

Troubleshooting

As per a discussion #36649 (comment 247000703) on a previously opened MR related to the seeding script, I have tried setting save_on_errors to true but am still not able to seed data.

Proposal

"Every time the CA seed script is executed, we create new, unique projects with all the necessary data (users, deployments, pipelines)" per @ahegyi in #195829 (comment 270941303).
