Discord.js variable does not exist when defined?

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);
    });
});

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.

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
    }
}
