Next.js Headタグの使い方

Last updated at Posted at 2022-11-03

Headタグの書式ミスでvercelデプロイ失敗

Nextで作成したWebアプリケーションをVercelでデプロイしたのですが、

react_devtools_backend.js:4026 TypeError: Cannot read properties of null (reading 'content')
...
...

ようなエラーが出てしまい、「サーバーサイド側で記述をミスったのかな...」
と思っていたのですが、色々見た結果nextのheadタグの書式で間違っていることが判明、、

<Head>
    <h1>
        <title>ログインページ</title> 
    <h1>
</Head>

このような記述をしていたのが原因でした。omg

正しくは以下ですね↓

<Head>
        <title>ログインページ</title> 
</Head> 

next初学者の方ご参考までに、以上
