ws throws TypeError: Cannot use 'in' operator to search for 'code' in undefined when with Deno

[NeuroWhAI]

Which package is this bug report for?

ws

Issue description

1. Use deno, Make a simple Discord bot.
2. Leave the bot running for a long time. (Maybe 1 day?)
3. The bot suddenly throws an error and dies.

Error : TypeError: Cannot use 'in' operator to search for 'code' in undefined
Location: https://github.com/discordjs/discord.js/blob/main/packages/ws/src/ws/WebSocketShard.ts#L794

If I manually modify the conditional statement locally as follows, the problem no longer occurs.
But I'm not sure if it's okay to do this.

onError(error) {
  if (error && "code" in error && ["ECONNRESET", "ECONNREFUSED"].includes(error.code)) {

I'm not sure if this is due to differences between Deno and Node.js, but I suspect it is.

Hi. Do you have a full stack trace? I'd like to see what invoked onError

[NeuroWhAI]

I will reproduce and get the trace log.

Here is a trace log. @didinele

If possible, would you be able to log event here so we can see what the payload is?

discord.js/packages/ws/src/ws/WebSocketShard.ts

Line 259 in 757bed0

this.onError(event.error);

[NeuroWhAI]

@Jiralite It was {}... 🤔

    connection.onerror = (event) => {
      console.log("=======================================");
      console.log(JSON.stringify(event));
      console.log("=======================================");
      this.onError(event.error);
    };

=======================================
{}
=======================================

That's most certainly a deno bug of some sort then, recommend reporting it.
