Next.js href interpolation failed for a dynamic route

href Interpolation Failed

Next.js could not build a dynamic route URL because not all required route parameters were supplied to Link, Router.push, or Router.replace.

href Interpolation Failedruntime

Observed message

href Interpolation Failed

Why it happens

  • A dynamic route href is missing one or more required params.
  • The pathname includes multiple dynamic segments but the query object is incomplete.
  • Client navigation code builds a route object without all segment values.

How to fix it

  1. Make sure every dynamic segment in the pathname has a matching value in query.
  2. Review Link, Router.push, and Router.replace calls for incomplete route objects.
  3. Test the specific link interaction because this error appears when the link is used.
