# Incompatible `href` and `as` values

#### Why This Error Occurred

Somewhere you are utilizing the `next/link` component, `Router#push`, or `Router#replace` with a dynamic route in your `href` that has an incompatible `as` value. The `as` value is incompatible when the path doesn't provide only the expected parameters for the dynamic route.

Note: this error will only show when the `next/link` component is clicked not when only rendered.

**Incompatible `href` and `as`**

```jsx
import Link from 'next/link'

export default function Page(props) {
  return (
    <>
      <Link href="/[post]" as="/post-1/comments">
        <a>Invalid link</a>
      </Link>
    </>
  )
}
```

**Compatible `href` and `as`**

```jsx
import Link from 'next/link'

export default function Page(props) {
  return (
    <>
      <Link href="/[post]" as="/post-1">
        <a>Valid link</a>
      </Link>
    </>
  )
}
```

#### Possible Ways to Fix It

Look for any usage of the `next/link` component, `Router#push`, or `Router#replace` and make sure that the provided `href` and `as` values are compatible
