Segmentation fault (core dumped) when listen to https using example WorkerThreads.js

[snowinszu]

code like this:

if (isMainThread) {

	/* The acceptorApp only listens, but must be SSL if worker apps are SSL and likewise opposite */
	const acceptorApp = uWS.SSLApp({
		key_file_name: 'misc/key.pem',
		cert_file_name: 'misc/cert.pem',
		passphrase: '1234'
	  }).listen(port, (token) => {
		if (token) {
		  console.log('Listening to port ' + port + ' from thread ' + threadId + ' as main acceptor');
		} else {
		  console.log('Failed to listen to port ' + port + ' from thread ' + threadId);
		}
	  });

  /* Main thread loops over all CPUs */
  /* In this case we only spawn two (hardcoded) */
  /*os.cpus()*/[0, 1].forEach(() => {
	
    /* Spawn a new thread running this source file */
    new Worker(__filename).on("message", (workerAppDescriptor) => {
		acceptorApp.addChildAppDescriptor(workerAppDescriptor);
	});
  });

  /* I guess main thread joins by default? */
} else {
  /* Here we are inside a worker thread */
  const app = uWS.SSLApp({
    key_file_name: 'misc/key.pem',
    cert_file_name: 'misc/cert.pem',
    passphrase: '1234'
  }).get('/*', (res, req) => {
    res.end('Hello Worker!');
  }).listen(4000, (token) => {
	if (token) {
		console.log('Listening to port ' + 4000 + ' from thread ' + threadId);
	  } else {
		console.log('Failed to listen to port ' + 4000 + ' from thread ' + threadId);
	  }
  });

  /* The worker sends back its descriptor to the main acceptor */
  parentPort.postMessage(app.getDescriptor());
}

Testing on ubuntu 24.04

I was also not able to get the worker thread example working. I used the following script:

import uWS from 'uWebSockets.js'
import { Worker, isMainThread, threadId, parentPort } from 'node:worker_threads'

const port = 9001
const __filename = new URL(import.meta.url).pathname

if (isMainThread) {
  const acceptorApp = uWS.App()
  acceptorApp.listen(port, (token) => {
    if (token) {
      console.log('Listening to port ' + port + ' from thread ' + threadId + ' as main acceptor')
    } else {
      console.log('Failed to listen to port ' + port + ' from thread ' + threadId)
    }
  })

  const threads = [0, 1]
  threads.forEach(() => {

    /* Spawn a new thread running this source file */
    new Worker(__filename).on('message', (workerAppDescriptor) => {
      acceptorApp.addChildAppDescriptor(workerAppDescriptor)
    })
  })

  /* I guess main thread joins by default? */
} else {
  /* Here we are inside a worker thread */
  const app = uWS.App().get('/*', (res, req) => {
    res.end('Hello Worker!')
  }).listen(4000, (token) => {
    if (token) {
      console.log('Listening to port ' + 4000 + ' from thread ' + threadId)
    } else {
      console.log('Failed to listen to port ' + 4000 + ' from thread ' + threadId)
    }
  })

  /* The worker sends back its descriptor to the main acceptor */
  parentPort?.postMessage(app.workerAppDescriptor)
}

There is no function called getDescriptor nor workerAppDescriptor property. Any feedback how to achieve this?
