Hi! Recently updated some packages and started running into this ts build error: 
node_modules/discord.js/typings/index.d.ts:986:14 - error TS2417: Class static side 'typeof Client' incorrectly extends base class static side 'typeof BaseClient'.
  The types returned by 'on(...)' are incompatible between these types.
    Property '[Symbol.asyncDispose]' is missing in type 'AsyncIterableIterator<any>' but required in type 'AsyncIterator<any[], any, any>'.

986 export class Client<Ready extends boolean = boolean> extends BaseClient {
                 ~~~~~~

  node_modules/typescript/lib/lib.esnext.disposable.d.ts:40:5
    40     [Symbol.asyncDispose](): PromiseLike<void>;
           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    '[Symbol.asyncDispose]' is declared here.

In case it is relevant, my tsconfig is pretty simple: 
{
    "compilerOptions": {
        "module": "NodeNext",
        "moduleResolution": "nodenext",
        "outDir": "dist",
        "sourceMap": true,
        "strict": true
    },
    "include": ["src/**/*"]
}
{
    "compilerOptions": {
        "module": "NodeNext",
        "moduleResolution": "nodenext",
        "outDir": "dist",
        "sourceMap": true,
        "strict": true
    },
    "include": ["src/**/*"]
}
Well, I jumped forward from typescript 5.2.0-dev.20230804; it being a weird dev build was one of the reasons I updated. I'll try reverting to those other versions and get back to you Looks like 5.5 works. Now I just gotta typeguard my message.channel.sends

:method: GuildChannel#isSendable() @14.16.3 Indicates whether this channel is sendable.

Let me check. The method I am using this in has the param specified as a TextBasedChannel, since that's what I was getting at the time So maybe I just need to update the param type Getting it from an interaction Still looks like a TextBasedChannel type Sorry, I was mixing two seperate examples. In one example, it's an interaction.channel, in the other it's a message coming from a messagecreate event Most of my bot has been updated to use slash commands, but I still have some that just read chat Either way, I'll be using that isSendable() Thank you for your help And bots don't get permission to send messages in GroupDMs? I assume 👍🏻 Again, I appreciate your help I thought I had, but I can double check later Thanks for the follow-up
