So, my server has channels for each user, and the name of the channel is their user id.

The way I want it to work is;

When a user DMs the bot with any message, the bot looks for that channel (the channel that's named as their user id) in the server and sends the content of the message it receieved in DMs, but I keep getting an error:

Cannot read property "send" of undefined

Here is my code

client.on("message", async (message) => {
    if (message.channel.type === "dm") {
        if (message.author.bot) return;

        var guild = client.guilds.cache.get("840120593311334410");

        const cha = message.author.id;
        var hsa = await guild.channels.cache.find((ch) => ch.name === cha);
        hsa.send("test");
    }
});
