Migrate a Vanilla forum to Discourse

/var/www/discourse# RAILS_ENV=production ruby script/import_scripts/vanilla.rb /shared/export.txt
/var/www/discourse/vendor/bundle/ruby/3.1.0/gems/activerecord-7.0.4.1/lib/active_record/connection_adapters/postgresql_adapter.rb:81:in `rescue in new_client’: We could not find your database: discourse. Which can be found in the database configuration file located at config/database.yml.

Gemfile는 통과했는데, 이제 이 오류가 발생합니다. 조언이 있을까요?
