Discord bot will not respond, shuts down - error-handling

Question

I am new to programming a Discord bot (and I love it), and it has problems responding. When I start it with node main.js, it works as normal until I do something like -ping, upon which it stops working.
Here is the error that I receive:
ReferenceError: clicent is not defined
at Client.<anonymous> (C:\Users\Eric Müller\Desktop\Discord bot\Main.js:27:9)
at Client.emit (events.js:315:20)
at MessageCreateAction.handle (C:\Users\Eric Müller\Desktop\Discord bot\node_modules\discord.js\src\client\actions\MessageCreate.js:31:14)

at WebSocket.emit (events.js:315:20)
at Receiver.receiverOnMessage (C:\Users\Eric Müller\Desktop\Discord bot\node_modules\ws\lib\websocket.js:825:20)
Here is my code:
const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = '-';
const fs = require('fs');
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands/').filter(file => file.endsWith('.js'));
for(const file of commandFiles){
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
}
client.once('ready', () => {
console.log('Codelyon is online!');
});
client.on('message', message =>{
if(!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase();
if(command === 'ping'){
client.commands.get('ping').execute(message, args);
}
});
client.login(' '); (DISCLAMER! THE TOKEN IS FILLED IN AND CORRECT)
ping.js:
module.exports = {
name: 'ping',
description: "this is a ping command!",
execute(message, args){
message.channel.send('pong!');
}
}

As the error suggests, you most likely have a typo somewhere in your code:
ReferenceError: clicent is not defined at Client. (C:\Users\Eric Müller\Desktop\Discord bot\Main.js:27:9)
The error tells you that at the beginning of line 27 in Main.js file, you have clicent, but it was probably supposed to be client.
