ウイザード形式フォームについて

ウイザード形式のサインインについて

Ruby on rails
ユーザー機能を実装中に以下のメッセージ、ターミナルに表示され、saveが出来ません。
最後のcreateにsaveする箇所で、rollbackしてしまう。

ターミナルのメッセージ

(0.2ms) BEGIN
User Exists (0.3ms) SELECT 1 AS one FROM users WHERE users.email = BINARY 'b@ne.jp' LIMIT 1
(0.1ms) ROLLBACK

試したこと

カラムにencrypted_passworとなっていたのでencrypted_passwordとコントローラーに記載していたがpasswordに変更
