title: Handling "Dynamic href is not Supported in the App Router" Error in Next.js
description: This document describes the dynamic href is not supported in the App Router error in Next.js and provides a solution to fix it.
---
## Why This Error Occurred
The "Dynamic `href` is not supported in the App Router" error happens when you try to use a dynamic `href` with `next/link` in the `app` directory.
The new client-side router in Next.js does not use a mapping of dynamic routes to URLs, but rather it leverages the URL directly. This means it doesn't support dynamic `href` use.
## Possible Ways to Fix It
You need to replace the dynamic `href` with a direct path in the `next/link` component. Here's a before and after comparison of what your code should look like:
**Before**
```jsx
<Link
href={{
pathname: '/route/[slug]',
query: { slug: '1' },
}}
>
link
</Link>
```
Or
```jsx
<Link href="/route/[slug]?slug=1">link</Link>
```
**After**
```jsx
<Link href="/route/1">link</Link>
```
In the revised code, the dynamic part of the `href` (`[slug]`) is replaced directly with the actual value (`1`), which simplifies the `href` and makes it a direct path.
