GuildDelete event triggers every time bot starts

[DomDom3333]

Please describe the problem you are having in as much detail as possible:
Every time I start the bot, the guildDelete event triggers. However while the guild object is valid, the name and member count is undefined. This results in an error.

Include a reproducible code sample here, if possible:
Can't be reproduced without this specific Token. May be related to Discord itself. Starting the bot with a different token fixes the issue.

bot.on("guildDelete", guild => {
    LOG.info(`Got booted from a Server!!!!!!!!\n- Name: ${guild.name}\n- Member Count: ${guild.memberCount}\nI'm now in ${bot.guilds.cache.size} Servers!`);
    Utils.contactAdmins(`Got booted from a Server!!!!!!!!\n- Name: ${guild.name}\n- Member Count: ${guild.memberCount}\nI'm now in ${bot.guilds.cache.size} Servers!`);
})

Further details:

• discord.js version: 12.4.1
• Node.js version: 12.18.1
• Operating system: Win10
• Priority this issue should have – please be realistic and elaborate if possible: Low-Medium

Relevant client options:

• partials: none
• gateway intents: none
• other: none

I am seeing the same running on Ubuntu 18.04

12.4.1 is no longer supported, please check 12.5.1 for the same issue.
If you can reproduce it add a listener for the websocket event and provide the output:

bot.ws.on("GUILD_DELETE", console.log);

Can reproduce on 12.5.1

Output that @almostSouji requested:

{ id: 'censored_guild_id' } 0

Good thing that I keep track of guild add / removes!

The guild in question actually removed my bot around 2021-02-24...

However every time that I start my bot, that guild will have a GuildDelete trigger for it immediately upon the bot starting.

I actually did not expect that to log anything. Since that's the case this behavior is coming directly from Discord and there is nothing we can do about it. Discord devs are aware but currently unsure about why it happens.

If you want to prevent it from, say sending the set message on guildDelete like I have, you could add something like

if (guild.name === undefined) return;

I also get the same error. This should be fixed with #5367

This also happened to me. The guild which triggered it was removed about a week ago.

Reopening, apparently this is something we need to handle (they should however not be considered unavailable)

From the discord developers server:

[...], it may be related to soft-deleted guilds .. essentially we now may delete a guild without triggering a full deletion, and attempts to join the guild (on session start) may result in this being spammed to gateway. this event can be safely ignored

This is handled in #5367
