Code: 
await parentChannel.threads.create({ // line 3643
    name,
    type: ChannelType.PrivateThread,
    invitable: false,
})
    .catch(
        // ...
await parentChannel.threads.create({ // line 3643
    name,
    type: ChannelType.PrivateThread,
    invitable: false,
})
    .catch(
        // ...
On both bots this happens when creating private threads. No code has been updated for ~2 days and this function runs very frequently (edit: not specific to private threads)

• What's your exact discord.js npm list discord.js and node node -v version? • Post the full error stack trace, not just the top part! • Show your code! • Explain what exactly your issue is. • Not a discord.js issue? Check out #useful-servers.

The thread is created but then an error is thrown Seems to be happening on 3 different bot tokens across 2 machines. Both [email protected] 
client.once(Events.ClientReady, async client => {
    console.log("ready")
    
    const channel = client.channels.cache.get("887784126713843803")
    await channel.threads.create({
        name: "test",
    })
})
client.once(Events.ClientReady, async client => {
    console.log("ready")

    await channel.threads.create({
        name: "test",

I'm curious. Seemed like it was related to caching threads when added but didn't really dig into it

Thanks. Seems like a really minor difference at a glance but clearly it matters
