@sentry/tracing 5.29.2

Description

At first I had the problem described in #2968 but I saw #2972 and added the methods I wanted to log:

new Tracing.Integrations.Express({ app, methods: ['get', 'post'] }),

This works great, except that it doesn't seem to handle nested middlewares.
I checked the code source and indeed it seems the wrapping only applies to the app or router parameter.

That means considering a code like this:

// index.ts
const app = express();

Sentry.init({
  dsn: "...",
  integrations: [
    new Tracing.Integrations.Express({ app, methods: ["get"] }),
  ],
  tracesSampleRate: 1.0,
});

app.get("/test", someHandler); // first endpoint

app.use("/api", require("./api")); // nested router


// api.ts
const router = express.Router();

router.get("/users", someHandler); // second endpoint

export default router;

• If we call /test we'll indeed get middleware.get corresponding to our first endpoint in the list of spans.
• If we call /api/users we'll only get middleware.use router corresponding to the nested router, but the second endpoint will not appear at all in the list of spans.
