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

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

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
