I have a problem in creating the main file for my discord bot. currently, i encountered a problem in trying to get my bot to work but sadly, this error message has been outputted from the console.

PS C:\Users\Kelvin Wang\Documents\Projects\DiscordBot> node index.js
node:internal/modules/cjs/loader:1170
    throw err;
     ^

SyntaxError: C:\Users\Kelvin Wang\Documents\Projects\DiscordBot\config.json: Unexpected end of JSON input

My code in index.js is this:

//initial discord initialization of client and library
// Require the necessary discord.js classes
const { Client, Intents } = require('discord.js');
const { token } = require('./config.json');
const dotenv = require('dotenv');

// Create a new client instance
const client = new Client({ intents: [Intents.FLAGS.GUILDS] });

// When the client is ready, run this code (only once)
client.once('ready', () => {
    console.log('Ferraribot is online!');
});

// Login to Discord with your client's token
client.login(token);

While my config.json looks like this:

{
"token": "token"
}

Any help would be much appreciated! This is my first time using stack overflow so I'm sorry for any wrong formatting that I've done. Thanks in advance!
