I've had an issue on DiscordJS with deno. Whenever I run this code I am getting this issue below.

[bartlomieju]

FYI support for discord.js was added in https://github.com/denoland/deno/pull/19412 and will be released tomorrow in v1.34.3. That said ClientReuqest.options.createConnection is still not supported and ignored entirely.

I encoutered a similar bug.

the source code is

// Construct your connection:
const connection = new Connection({
    websocket: 'wss://fullnode.testnet.sui.io',
    faucet: 'https://faucet.testnet.sui.io/gas',

// connect to Testnet
const provider = new JsonRpcProvider(connection);

const promptSub = await provider.subscribeEvent({

Same for me using puppeteer

import { join } from "https://deno.land/std@0.197.0/path/mod.ts";
import denoDir from "https://deno.land/x/dir/mod.ts";
import puppeteer from 'npm:puppeteer-core@21.0.2';
import {install, resolveBuildId} from "npm:@puppeteer/browsers@1.5.1"

const {executablePath} = await install({
      browser: 'chrome',
      buildId: '113.0.5672.0',
      cacheDir: join(denoDir('cache'), "puppeteer")
});

const browser = await puppeteer.launch({
      headless: false,
      executablePath, 
});

const page = await browser.newPage();

await page.setContent(`<p>test</p>`, { waitUntil: 'networkidle2' });

[acrodrig]

Is there a workaround? I am trying to use Deno with the mqtt and I get the same issue. Thanks.

[theandym]

I'm also experiencing this issue with CCXT — specifically with CCXT Pro and its connection via websockets for the watch* methods.

[uynilo9]

the same as me with npm:discord.js

[SoftwareAndOutsourcing]

I can reproduce this issue in #21096.

[Abdillah]

I'm reproducing this on npm:selenium-webdriver which uses Chrome Debug Protocol (using websocket, ws package). Using the following code:

import { Builder } from 'npm:selenium-webdriver';

const builder = new Builder()
.forBrowser(Browser.CHROME)

try {
    const driver = await builder.build();
    const cdp = await driver.createCDPConnection('page');
} catch(e) {
    console.log("ERR", e)
}

+1 having this issue with Discord JS

[worotyns]

Same in npm:@slack/bolt

[mariusheil]

I am also using mqtt.js and while everything seems to work, the same error is thrown and it would be nice if it were fixed. Not sure of the implications when this error is thrown.

[vanvanni]

+1, Also encountering this in Discord.JS and still have to start with MQTT.

[jpagand]

I am also using mqtt.js and while everything seems to work, the same error is thrown and it would be nice if it were fixed. Not sure of the implications when this error is thrown.

For me, the websocket reconnection logic doesn't work

[gardc]

+1 having this issue with Discord JS

Same here, still an issue.

[ducan-ne]

Same here, this blocks me from using port checking libs, wondering any workaround for that

[Sunf3r]

Same in npm:baileys

[maheshbansod]

Issue still exists in 1.45.2

[mariusheil]

For npm:mqtt, this is really annoying as it is the only major mqtt implementation that can be used for deno. All the other implementations are not maintained anymore. At least I was not able to find a maintained package.
