Proxy not working from version v6.0.0-beta.20 to v6.0.8

[dhilip89]

Describe the bug Proxy is throwing different error on different environment with the version (from v6.0.0-beta.20 to v6.0.8), it was working fine in v6.0.0-beta.19.

On Windows machine:

Waiting for the debugger to disconnect... node:internal/process/promises:289 triggerUncaughtException(err, true / fromPromise /); ^

[Error: Unknown error] { errno: 10045, code: '' }

On Ubuntu machine:

Debugger attached. Waiting for the debugger to disconnect... node:internal/process/promises:391 triggerUncaughtException(err, true / fromPromise /); ^

[Error: Operation not supported] { errno: 95, code: 'ENOTSUP' }

Reproducing Using example from the official documentation:

import { Proxy, Router, Dealer } from "zeromq"

// Proxy between a router/dealer socket for 5 seconds.
const proxy = new Proxy(new Router, new Dealer)
await proxy.frontEnd.bind("tcp://*:3001")
await proxy.backEnd.bind("tcp://*:3002")
setTimeout(() => proxy.terminate(), 5000)
await proxy.run() // <-- This line throws unknown error on Windows, ENOTSUP on Linux

Downgrade zeromq.js to v6.0.0-beta.19 then the code will not throw error.

Expected behavior Proxy should be working correctly without throwing error like with previous version.

Tested on

• OS: Windows Server 2022, Ubuntu 24.10
• ZeroMQ.js versions: 6.0.0-beta.19, 6.0.0-beta.20, 6.0.0 - 6.0.8
• Node,js version: 20.11.1, 20.16.0

@dhilip89 Could you confirm that the latest release fixed this or not?

@dhilip89 Could you confirm that the latest release fixed this or not?

Just upgraded to latest version (6.1.1), everything seems working as expected on both Windows and Linux machines.
