No Document Import in Page

    Prevent importing next/document outside of pages/_document.js.

    Why This Error Occurred

    next/document was imported in a page outside of pages/_document.js (or pages/_document.tsx if you are using TypeScript). This can cause unexpected issues in your application.

    Possible Ways to Fix It

    Only import and use next/document within pages/_document.js (or pages/_document.tsx) to override the default Document component:

    // pages/_document.js
    import Document, { Html, Head, Main, NextScript } from 'next/document'
    class MyDocument extends Document {
    export default MyDocument
