.trace() never get invoked if aot=false

[hisamafahri]

What version of Elysia is running?

^1.2.10

What platform is your computer?

Darwin 24.3.0 arm64 arm

What steps can reproduce the bug?

• In an elysia project, copy the following code (adjusted from Trace docs):

import { Elysia } from "elysia";

const app = new Elysia({ aot: false })
  .trace(async ({ onHandle }) => {
    onHandle(({ begin, onStop }) => {
      onStop(({ end }) => {
        console.log('handle took', end - begin, 'ms')
      })
    })
  })
  .get('/', () => 'Hi')
  .listen(3000)

console.log(
  `🦊 Elysia is running at ${app.server?.hostname}:${app.server?.port}`
);

• Run the project, and call http://localhost:3000. The API itself should return HTTP 200.

What is the expected behavior?

It should display handle took xxms.

What do you see instead?

If using aot=false, the process doesn't log anything in the .trace() method (no console.log values displayed). But, on the other hand, usingaot=true, it works as intended.

Additional information

I highly suspects that this problem also impact (at least) the @elysiajs/opentelemetry, since it also utilizes the .trace() handler (see also: elysiajs/opentelemetry#11).

Have you try removing the node_modules and bun.lockb and try again yet?

Yes
