No Duplicate Head
Prevent duplicate usage of
<Head>inpages/_document.js.
Why This Error Occurred
More than a single instance of the <Head /> component was used in a single custom document. This can cause unexpected behavior in your application.
Possible Ways to Fix It
Only use a single <Head /> component in your custom document in pages/_document.js.
// pages/_document.js
import Document, { Html, Head, Main, NextScript } from 'next/document'
class MyDocument extends Document {
static async getInitialProps(ctx) {
//...
}
render() {
return (
<Html>
<Head />
<body>
<Main />
<NextScript />
</body>
</Html>
)
}
}
export default MyDocument
