Hi @quartz spindle. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

The error message you're seeing, TypeError: Cannot read properties of undefined (reading 'clone'), suggests that request.nextUrl is undefined at the time when you're trying to clone it. This could be due to the fact that nextUrl is not available in the request object you're passing to your page function.
However, based on the information provided in the extracts, it's not clear why nextUrl would be undefined. The extracts do not provide enough information to diagnose this issue.
As for the usage of cookies, in Next.js, you can retrieve request-based data based on the Node.js HTTP API. For example, you can retrieve the req object from getServerSideProps and use it to retrieve the request's cookies and headers. In the app directory, new read-only functions are exposed to retrieve request data, such as headers() and cookies(). These can be used inside Server Components to retrieve request headers and cookies respectively.
Here is an example of how to use cookies from the extracts:
import { cookies, headers } from 'next/headers'
async function getData() {
const authHeader = headers().get('authorization')
return '...'
}
export default async function Page() {
// You can use `cookies()` or `headers()` inside Server Components
// directly or in your data fetching function
const theme = cookies().get('theme')
const data = await getData()
return '...'
}

If you're still encountering issues, I would recommend checking the official Next.js documentation or reaching out to the Next.js community for further assistance.

@inner steeple but i want to redirect home when user is not found
inner steepleBOT
Let me check the knowledge base for you. One moment! :books:
Based on the information provided in the extracts, you can use the NextResponse.rewrite() method to redirect to a different page. In your case, you want to redirect to the home page when the user is not found. Here's how you can do it:
import { cookies, NextResponse } from 'next/server';
import type { NextRequest } from 'next/server'
async function page(request: NextRequest) {
const usernameCookie = cookies().get('Username');
if (!usernameCookie) {
return NextResponse.rewrite('/')
}
// rest of your code
}
In this code, if the usernameCookie is not found, the NextResponse.rewrite('/') method is called, which will redirect to the home page.
Please note that this is based on the information provided in the extracts and may need to be adjusted based on your specific application setup.

@inner steeple Error: URL is malformed "/". Please use only absolute URLs - https://nextjs.org/docs/messages/middleware-relative-urls
inner steepleBOT
Let me check the knowledge base for you. One moment! :books:
The error message you're seeing is due to the use of a relative URL in your middleware. As per the Next.js documentation and the information provided in the extracts, Next.js middleware currently only supports absolute URLs for redirection.
If you're trying to redirect to the home page, you should use an absolute URL. An absolute URL includes the protocol (http or https), hostname, and path. For example, if your website is <https://example.com,> you should redirect to <https://example.com/> instead of just /.
Here's how you can modify your code:
import { NextResponse } from 'next/server';
import type { NextRequest } from 'next/server'
async function page(request: NextRequest) {
const usernameCookie = cookies().get('Username');
if (!usernameCookie) {
return NextResponse.rewrite('<https://example.com/'>)
}
// rest of your code
}
Please replace '<https://example.com/'> with your actual website URL.
For more information, you can refer to the Next.js Documentation (https://nextjs.org/docs/messages/middleware-relative-urls).

@inner steeple Error: Only plain objects, and a few built-ins, can be passed to Client Components from Server Components. Classes or null prototypes are not supported.
inner steepleBOT
Let me check the knowledge base for you. One moment! :books:
The error message you're seeing is related to the way data is passed between Server Components and Client Components in Next.js. According to the Next.js documentation, when passing data between a Server and Client Component through props, the data is serialized (converted to a string) for use in the browser. However, not all types of data can be serialized. Only plain objects and a few built-ins can be passed to Client Components from Server Components. Classes or objects with null prototypes are not supported (source (https://nextjs.org/docs/app/building-your-application/configuring/typescript#passing-data-between-server--client-components)).
This issue was also discussed in a GitHub issue where users were seeing a similar error message when trying to pass objects with null prototypes from Server Components to Client Components. One user suggested converting the data to a string before passing it to the page for use (source (https://github.com/vercel/next.js/issues/47447)).
Here's an example of how you might do this:
data={JSON.parse(JSON.stringify(unit))}
