I'm making a banana machine and it grabs a random banana image in a directory i created inside the fun directory heres my code:

var fs = require('fs');
  fs.readdir('./fun/bananas/', (err, files) => {
    if (err) console.log(err);

    let bonannapics = files.filter(f => f.split('.').pop() === 'png');

    let chosenFile = bonannapics[Math.floor(Math.random() * bonannapics.length)]
    const attachment = new MessageAttachment(chosenFile)
    let bananaembed = new MessageEmbed()
      .setTitle("Bonana Machine")
      .setColor(config.color)
      .setDescription("here is your banana!")
      .attachFiles(attachment)
      .setImage(attachment)
      .setFooter(config.footer)
    message.channel.send(bananaembed);
  });

Heres the error:

(node:6072) UnhandledPromiseRejectionWarning: Error: ENOENT: no such file or directory, stat '/home/runner/Gloozzys-Treehouse/banana3.png'

heres the folder structure: folderstructure picture

it thinks the image is in a different directory but I don't know why, if anyone could help me solve this that would be great.
