Here, you would be setting http.route as the target, not the route.
The target is /posts/42, while the route is /posts/:id.
If we cannot get the route, it should not be set.
See https://github.com/open-telemetry/semantic-conventions/blob/b77c881ad68dca7bb7af2c97899a0ef64357c47c/docs/http/http-spans.md#http-server-semantic-conventions

This is using HTTPTargetKey, so it's setting the http.target attribute twice, not http.route.
