why won't my commands send?

client.on('message', message => {
    if (!message.content.startsWith(prefix) || message.auther.bot) return;
    
    const args = message.content.slice(prefix.length).split(/ +/);
    const command = args.shift().toLowerCase();

    //test cmd

    if (command === 'test'){
       message.channel.send('The Bot is working!') 
    }
})
