Notes

Based on the error message, the main issue is that the NextRouter is not mounted when trying to render the page. This typically happens when using router-related hooks or components in a server-side context. To fix this, we need to make sure that router-dependent code is only executed on the client side. Here's how to fix the issue:
In your page.tsx or layout.tsx file (whichever contains the router-dependent code), add the following at the top of the file:
jsx
'use client'
Replace any usage of useRouter from 'next/router' with useRouter from 'next/navigation' in the App Router (for Next.js 13+):
jsx
import { useRouter } from 'next/navigation'
If you're using any router-dependent components or hooks, wrap them in a client-side only component. Create a new component, let's call it ClientSideWrapper.tsx:
jsx
'use client'

import { useRouter } from 'next/navigation'
import React from 'react'

const ClientSideWrapper = ({ children }) => {
const router = useRouter()
return <>{children}</>
}

export default ClientSideWrapper
In your main page component, use this wrapper:
jsx
import ClientSideWrapper from './ClientSideWrapper'

const Page = () => {
return (
<ClientSideWrapper>
{/* Your page content here */}
</ClientSideWrapper>
)
}

export default Page
For the FAQ component warning, wrap the faqs array initialization in a useMemo hook:
jsx
import React, { useMemo, useEffect } from 'react'

const FAQ = () => {
const faqs = useMemo(() => [
// Your FAQ array here
], [])

useEffect(() => {
// Your effect code here
}, [faqs])

// Rest of your component
}
These changes should resolve the NextRouter mounting issue and the FAQ warning. Make sure to apply these changes to all components that use router-dependent code or have similar warnings.
