What are handleHardNavigation Errors?

Handle hard navigation errors occur in Next.js applications when trying to redirect to the same page. These errors show up with the message Error: Invariant: attempted to hard navigate to the same URL.

What causes handleHardNavigation Errors?

When you see the error Invariant: attempted to hard navigate to the same URL, it means that that browser tried to load the page of the same URL. There are a number of reasons this might happen:

  • Loading a page after a new build (explanation)
  • You’re using an older version of Next.js (related issue)
  • Your app is redirecting to the same URL in middleware.

Custom 404 Page

If you are seeing the redirect when handling a 404, you can create a custom page named [...myErrorPage] and treat that as your 404 page (source)

Filter out Error

As a last resort, you can filter out these errors from Sentry altogether. To do this, edit your Sentry.init as shown below:
