Discord.js variable does not exist when defined? - discord

Question

I'm trying to code a bot command using discord.js and Minecraft-server-util but my code is not using the const I defined and is saying it does not exist. If you spot any other problems you can correct me on them.
client.on('message', message => {
if (message.content === `${prefix}javaserverstatus`) {
const args = message.content.slice(prefix.length).trim().split(' '); // this is where args is defined.
if (!args.length) {
return message.channel.send(`You didn't provide a server, ${message.author}!`); // checks if args exist
}
if (args.length > 1) {
return message.channel.send(`Wrong input! EG. play.hypixel.net, ${message.author}`); // checks if there are only 1 arguments
}
}
const util = require('minecraft-server-util');
var serverinfo = null
util.status(args) // This code is giving an error saying args does not exist.
.then((response) => {
console.log(response);
serverinfo = response;
const embed = new Discord.MessageEmbed()
.setTitle('play.hypixel.net Server Status')
.setColor(0xff0000)
.setDescription('IP: ' + response.host + '\n' + 'Port: ' + response.port + '\n' + 'Version: ' + response.version + '\n' + 'Online Players: ' + response.onlinePlayers.toString() + '\n' + 'Max Players: ' + response.maxPlayers.toString() + '\n');
message.channel.send(embed);
})
.catch((error) => {
console.error(error);
});
});

Answer 1

The error is due to the scope that you've defined args in.
args is defined in your first if statement when it should be defined a line above.
const args = message.content.slice(prefix.length).trim().split(' ');
if (message.content === `${prefix}javaserverstatus`) {
// this is where args is defined.
if (!args.length) {
return message.channel.send(`You didn't provide a server, ${message.author}!`); // checks if args exist
}
if (args.length > 1) {
return message.channel.send(`Wrong input! EG. play.hypixel.net, ${message.author}`); // checks if there are only 1 arguments
}
}

You've defined args in a if statement. You need to put it out of there.
client.on('message', (message) => {
const args = message.content.slice(prefix.length).trim().split(' ') // this is where args is defined.
if (message.content === `${prefix}javaserverstatus`) {
if (!args.length) {
return message.channel.send(`You didn't provide a server, ${message.author}!`) // checks if args exist
}
if (args.length > 1) {
return message.channel.send(`Wrong input! EG. play.hypixel.net, ${message.author}`) // checks if there are only 1 arguments
}
}
const util = require('minecraft-server-util')
var serverinfo = null
util
.status(args) // This code is giving an error saying args does not exist.
.then((response) => {
console.log(response)
serverinfo = response
const embed = new Discord.MessageEmbed()
.setTitle('play.hypixel.net Server Status')
.setColor(0xff0000)
.setDescription('IP: ' + response.host + '\n' + 'Port: ' + response.port + '\n' + 'Version: ' + response.version + '\n' + 'Online Players: ' + response.onlinePlayers.toString() + '\n' + 'Max Players: ' + response.maxPlayers.toString() + '\n')
message.channel.send(embed)
})
.catch((error) => {
console.error(error)
})
})
If this isn't working, pls send me the command you sent in the discord chat.
