How do you delete certain messages from a specific username not ID

Question

twitchClient.on('timeout', async (channel, username, user, reason, duration) => {

    discordClient.on('message', async (message, messages) => {
        async function deleteMessage() {
            await discordClient.channels.cache.get("901568598538063932")
            .messages.fetch({limit: null})
            .then(message.delete(messages.first(user["display-name"]).author.name))
        }
        await deleteMessage()
    })
        
    async function sendMessage() {
        const request = new XMLHttpRequest();
        request.open("POST", "API url");
        
        request.setRequestHeader('Content-type', 'application/json');

        const users = { 
        username: "User Timed Out",
        avatar_url: 'https://i.imgur.com/GUrbNsB.jpg',
        content: `**${username} has been timed out for ${duration} seconds.**`
        }
        request.send(JSON.stringify(users));
    }

    await sendMessage()
});

Note: This code is for Discord.js v13.3.0

As stated by the error, you're trying to access an undefined variable called messages. This is because you did not define it in the then() arguments, you instantly went to a callback.

then() is a function that allows for you to provide parameters to add. You can simply put the collection of messages as one variable called messages and pass it to the callback accordingly.

// DON'T do this
messages.fetch({limit: null})
            .then(message.delete(messages.first(user["display-name"]).author.name))

// DO this
messages.fetch({limit: null})
            .then((messages) => message.delete(messages.first(user["display-name"]).author.name))
