When I try to create account it fails, and rollback

Loading production environment (Rails 5.0.1) irb(main):001:0> Account.create(email: "[email protected]", password: "yourpassword", password_confirmation: "yourpasword") (0.3ms) begin transaction Account Exists (0.6ms) SELECT 1 AS one FROM "accounts" WHERE "accounts"."email" = ? LIMIT ? [["email", "[email protected]"], ["LIMIT", 1]] (0.3ms) rollback transaction => #<Account id: nil, email: "[email protected]", created_at: nil, updated_at: nil, authentication_token: nil> irb(main):002:0>
