• any other relevant information: –

What are you trying to achieve or the steps to reproduce?

Experimenting with bun.

import * as Hapi from '@hapi/hapi';

// this is necessary, because bun does not support this perf_hooks api right now
// <https://github.com/oven-sh/bun/issues/5804>
const PerfHooks = require('perf_hooks');
PerfHooks.performance.eventLoopUtilization = function() {}

const init = async () => {
    const server = Hapi.server({
        port: 4000,
        host: 'localhost'
    });

    server.route({
        path: "/api/test",
        method: "POST",
        handler: function() {
            console.log("successful")
            return {status: "ok"}
        }
    })

    await server.start();
    console.log('Server running on %s', server.info.uri);
};

init();

Steps to reproduce

• Install bun: https://bun.sh/
• Install dependencies: bun install --backend=copyfiles
• Run server bun run index.ts
• Now you should see Server running on http://localhost:4000
• Now run a curl request to the recently added endpoint:

curl --request POST \
  --url http://localhost:4000/api/test \
  --header 'Content-Type: application/json' \
  --data '{}'

What was the result you got?

Received 500 status code from the server. Seems like it throws through this line in wreck:

What result did you expect?

I would expect the same behavior as for node environment

@raphael-papazikas If a nodejs replica doesn't run Hapi, but Hapi runs in anything Node 16+, then it's not Hapi, it's the nodejs replica. I think the onus is on you guys to find out where the issue lies and report it to the Bun team. You may be solving a critical problem where Bun does not in fact behave like NodeJS.
