SpringBootで作成したページをブラウザに表示させたい
(エラーメッセージが長いので記事も長くなっております。。)
Javaを独学で学んでいる者です。
先日、SpringBootを使用してWebアプリケーションを作成しようと思い、下記ページを参考にコードの写経を行っておりました。
https://www.zunouissiki.com/spring-boot-register-postgressql/
しかし、同じようにコーディングしてもブラウザで表示させようとした時に
Whitelabel Error Page
とエラーが表示されてしまいます。
エラーメッセージから原因を追っかけてみて、都度調べて修正を試みたのですが中々上手くいかず、、
是非皆さんのお力をお借りしたく、気づいた点や間違っている箇所がありましたらご教示お願いしたく存じます。

自分で試したこと
エラーメッセージを見てみると、form.htmlのline14で何か起こっていると書かれているようでしたので、
input type="text" th:field="{name}"
span class="errorStr" th:errors="{name}"
をコメントアウトしたら次々とage,business,emailの箇所でも同様のエラーが表示され、
全てコメントアウトしたところ、ブラウザに表示はされたのですが、入力フォームが表示されなくなってしまいました。
初歩的な質問で恐縮ですが、コメント及びこういったメッセージが表示されたらメッセージのこの部分を読むと良いなどありましたらご教示いただけますと幸いです。
よろしくお願いします。
