title: '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 filename="pages/blog.js"
import Link from 'next/link'
export default function Page(props) {
return (
<>
Invalid link
>
)
}
```
**Compatible `href` and `as`**
```jsx filename="pages/blog.js"
import Link from 'next/link'
export default function Page(props) {
return (
<>
Valid 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
