so I am learning node JS and trying to make a discord bot with it and I am having troubles.

module.exports = {
    name: "gabe",
    description: "gabe",
    execute(message, args) {
        var fs = require("fs");
        var files = fs.readdirSync("./gabe/");
        let chosenFile = files[Math.floor(Math.random() * files.length)];
        const fileDirectory = "./gabe/";
        const filePicture = fileDirectory.concat(chosenFile);
        message.channel.send({ files: filePicture });
    },
};

I am trying to select a random picture from a folder (./gabe/), but I am getting 'FILE_NOT_FOUND'

In my code I am randomly selecting a .png from the ./gabe/ folder and trying to concat it to make it './gabe/name.png' so that the discord bot can dipsplay it.
