TypeError: fn.bind is not a function?

Question

JavaScript

Hello.
I'm trying to make a mute command. Its essence is to restrict the user from writing text. That is, he will not have writing privileges and, as planned, he will not be able to.
But an error occurs.
Here is the code:

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

module.exports = class MuteCommand extends Command {
  constructor(client) {
    super(client, {
      name: 'mute',
      memberName: 'mute',
      group: 'guild',
      description: 'mute',
      guildOnly: true,
      userPermissions: ['ADMINISTRATOR']
    });
  }

 async run(message, args) {
    let tomute = message.guild.member(message.mentions.members.first() || message.guild.members.get(args[0]));
    let mod = message.author
    let muterole = message.guild.roles.find(`name`, "Muted");
     if (!muterole) {
      try{
      muterole = await message.guild.createRole({
        name: "Muted",
        color: "#000000",
        permissions:[]
      })
      message.guild.channels.forEach(async (channel, id) => {
        await channel.overwritePermissions(muterole, {
            SEND_MESSAGES: false,
            ADD_REACTIONS: false
        });
      });
    }catch(e){
      console.log(e.stack);
    }
  }
   await tomute.addRole(muterole.id)
   const muteembed = new RichEmbed()
   .setTitle("**Мут**")
   .addField('Пользователь', `<@${tomute.id}>`, true)
   .addField('Модератор', `${mod}`, true)
   .setColor('#FF0000')
   message.embed(muteembed);
 }
};
