Deno / Websocket error

To start with, as I understand it, Deno is not officially supported. That said, from what I have been reading, it seemed like there was a reasonable chance of djs working with Deno since it added support for npm packages. I would really like to use Deno for my bot, so I gave it a go... Unfortunately, no dice -- I'm getting an error when djs is attempting to construct a WebSocket. I'm wondering if this is a familiar problem, or if anyone has an idea for what may be a fix for this. Here is the error when I attempt to run (I use "deno task simple" to run it):

error: Uncaught (in promise) SyntaxError: Invalid protocol value.
    at new WebSocket (ext:deno_websocket/01_websocket.js:203:13)
    at WebSocketShard.internalConnect (file:///Users/redacted/Library/Caches/deno/npm/registry.npmjs.org/@discordjs/ws/1.1.0/dist/index.js:675:24)
    at eventLoopTick (ext:core/01_core.js:168:7)

deno.json

{
  "tasks": {
    "simple": "deno run --allow-env --allow-read --allow-net --watch ./src/simple_main.ts"
  },
  "imports": {
    "discord.js": "npm:discord.js@^14.15.2",
    "dotenv": "npm:dotenv@^16.4.5"
  }
}

{
  "tasks": {
    "simple": "deno run --allow-env --allow-read --allow-net --watch ./src/simple_main.ts"
  },
  "imports": {
    "discord.js": "npm:discord.js@^14.15.2",
    "dotenv": "npm:dotenv@^16.4.5"
  }
}

simple_main.ts

import { Client } from "npm:discord.js";
import dotenv from "npm:dotenv";

dotenv.config();

const client = new Client({ intents: [] });

await client.login(Deno.env.get('TOKEN'))
  .then(() => {
    console.log(`🟩 [LOGIN] Client logged!`);
  })
  .catch((err) => console.error(`🟥 [LOGIN] ${err}`));

import { Client } from "npm:discord.js";
import dotenv from "npm:dotenv";

dotenv.config();

const client = new Client({ intents: [] });

await client.login(Deno.env.get('TOKEN'))
  .then(() => {
    console.log(`🟩 [LOGIN] Client logged!`);
  })
  .catch((err) => console.error(`🟥 [LOGIN] ${err}`));

The error is pointing at index.js in djs, which is doing this:

const connection = new WebSocketConstructor(url, {
  handshakeTimeout: this.strategy.options.handshakeTimeout ?? void 0
});

const connection = new WebSocketConstructor(url, {
  handshakeTimeout: this.strategy.options.handshakeTimeout ?? void 0
});

The tooltip is telling me arg2 should be a string | string[] | undefined which is probably why the underlying code is throwing the error. Again, I understand there isn't any official support, but if there's a workaround for this that allows me to continue using Deno, I would appreciate any ideas. In case it matters, deno --version:

deno 1.43.1 (release, x86_64-apple-darwin)
v8 12.4.254.12
typescript 5.4.3

deno 1.43.1 (release, x86_64-apple-darwin)
