Why the Uptime command gives me an error? ';' expected Discord.js

Question

I am trying to put a command that tells you the uptime like "0d 2h 37m 27s" but I get an error.

This is the status.js code:

const { Command } = require('discord.js-commando');
const { MessageEmbed } = require('discord.js');

module.exports = class statusCommand extends Command {
  constructor(client) {
    super(client, {
      name: 'status',
      group: 'other',
      memberName: 'status',
      guildOnly: true,
      description: 'Show the status of the bot!'
    });
  }

  let totalSeconds = (client.uptime / 1000);
  let days = Math.floor(totalSeconds / 86400);
  totalSeconds %= 86400;
  let hours = Math.floor(totalSeconds / 3600);
  totalSeconds %= 3600;
  let minutes = Math.floor(totalSeconds / 60);
  let seconds = Math.floor(totalSeconds % 60);

      async run(message, args) { 
    const statusEmbed = new MessageEmbed()
      .setColor('#6c6c6c')
      .setTitle('About Musik')
      .setDescription('Made by TheRedyYT')
      .addField('• Test', '```Test```', true)
      .addField('• Test', '```Test```', true)
      .addField('• Uptime', `\`\`\`${days} days, ${hours} hours, ${minutes} minutes and ${seconds} seconds\`\`\``, true)
      .addField('• Test', '```Test```', true)
      .addField('• Category Count', `\`\`\`${message.guild.channels.cache.filter(channel => channel.type == "category").size}\`\`\``, true)
      .addField('• Text Channel Count', `\`\`\`${message.guild.channels.cache.filter(channel => channel.type == "text").size}\`\`\``, true)
      .addField('• Voice Channel Count', `\`\`\`${message.guild.channels.cache.filter(channel => channel.type == "voice").size}\`\`\``, true)
      .addField('• Server Count', `\`\`\`${this.client.guilds.cache.size}\`\`\``, true)
    message.channel.send(statusEmbed);
}}

And this the error in the console:

/home/container/commands/other/status.js:15
  let totalSeconds = (client.uptime / 1000);
      ^^^^^^^^^^^^
