Somewhere you are utilizing the `next/link` component, `Router#push`, or `Router#replace` with a relative route in your `href` that has an external `as` value. The `as` value must be relative also or only `href` should be used with an external URL.
Note: this error will only show when the `next/link` component is clicked not when only rendered.
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
