 Calling `next()` with this signature will create a new `Request` object using the old `ctx.request`. This means that trying to consume `Request.body`, either before or after this rewrite, will throw a runtime error. This error is often raised with [Astro Actions that use HTML forms](/en/guides/actions/#call-actions-from-an-html-form-action). In these cases, we recommend handling rewrites from your Astro templates using `Astro.rewrite()` instead of using middleware.
