// Place your client and guild ids here
const clientId = 'myclientidisprivatern';

for (const file of commandFiles) {
	const command = require(`./commands/${file}`);
	commands.push(command.data.toJSON());
}

One of your commands doesn't have a data property exported. You should make sure no command files are empty and export the command builder as data
