Error when Network Connection Fails in discord.js on Deno

[speedfighter]

When the network connection encounters an error, I receive the following error from discord.js

Uncaught TypeError: Cannot use 'in' operator to search for 'code' in undefined
    at WebSocketShard.onError (file:///C:/Users/fabia/AppData/Local/deno/npm/registry.npmjs.org/@discordjs/ws/1.1.1/dist/index.js:1065:16)

    at eventLoopTick (ext:core/01_core.js:175:7)

However, when I test the same code with Node.js, this error does not occur. According to the discord.js github (Github discord.js Issue), the issue seems to be related to Deno.

Version: Deno 2.0.0
