Duplicate messageUpdate events in sharded bot

I'm receiving duplicate messageUpdate events and I'm not sure why. I have tried storing messageId in redis and checking it before sending message, but still it somehow bypasses it. Is it some sort of retry event? It's kind of similar to a let's say a bump reminder bot Relevant code: messageUpdate.ts

if (utils.invalidCondition(newMessage)) return;
const messageUpdate = new MessageHandler();
const handler = messageUpdate.createHandler(newMessage.interaction!.commandName);
await handler.messageUpdate(oldMessage, newMessage);

if (utils.invalidCondition(newMessage)) return;
const messageUpdate = new MessageHandler();
const handler = messageUpdate.createHandler(newMessage.interaction!.commandName);
await handler.messageUpdate(oldMessage, newMessage);

MessageHandler

export class MessageHandler {
    constructor() {
        // do nothing.
    }

    createHandler(commandName: string): CreateHandlerReturnType {
        switch (commandName) {
            case "x":
                return new XHandler();
             // ...
        }
    }
}

export class MessageHandler {
    constructor() {
        // do nothing.
    }

    createHandler(commandName: string): CreateHandlerReturnType {
        switch (commandName) {
            case "x":
                return new XHandler();
             // ...
        }
    }
}

XHandler

export class XHandler extends BaseMessageHandler {
  async messageUpdate(oldMsg: Message<boolean> | PartialMessage, newMsg: Message<boolean> | PartialMessage): Promise<void> {
   if (newMsg.embeds[0].title !== "Something") return;
   await newMsg.reply({ content: "Test" })
}

export class XHandler extends BaseMessageHandler {
  async messageUpdate(oldMsg: Message<boolean> | PartialMessage, newMsg: Message<boolean> | PartialMessage): Promise<void> {
   if (newMsg.embeds[0].title !== "Something") return;
   await newMsg.reply({ content: "Test" })
}

Scheduled message causes duplicate messages in sharded app

I have a sharded bot that sends reminders, but sometimes the bot sends duplicate messages. I'm not sure how to prevent this. I've tried: - Storing the messageId in redis for 10 mins after successfully sending a message, then checking if redis has the messageId before sending, if not found, I send the message - Implemented mutex I've observed duplicate reminders are being sent when too many messages are sent Yet duplicate reminders are being sent. I'm not sure if this is the correct, what's the standard way to do reminders in a sharded bot?

Getting original userID of slash command via Button Interaction

Hey, so I'm using a button Handler. But everyone can interact with the button. How do I restrict the button to be usable by the user who ran the slash command from which the button originated? (I use the interactionCreate event to reply to the buttons, so I can only get the buttonInteraction). I don't wanna use db
