Discord.js ReferenceError: channel is not defined

I'm using the discordjs bot guide and copied their help command from the GitHub. However the code gives an error. I've tried almost every solution I could find for the ReferenceError I'm getting. What am I doing wrong?
My code:
const { prefix } = require('../../config.json');
module.exports = {
name: 'help',
description: 'List all of my commands or info about a specific command.',
aliases: ['commands'],
usage: '[command name]',
cooldown: 5,
execute(message, args) {
const data = [];
const { commands } = message.client;
if (!args.length) {
data.push('Here\'s a list of all my commands:');
data.push(commands.map(command => command.name).join(', '));
data.push(`\nYou can send \`${prefix}help [command name]\` to get info on a specific command!`);
return message.author.send(data, { split: true })
.then(() => {
if (message.channel.type === 'dm') return;
message.reply('I\'ve sent you a DM with all my commands!');
})
.catch(error => {
console.error(`Could not send help DM to ${message.author.tag}.\n`, error);
message.reply('it seems like I can\'t DM you!');
});
}
const name = args[0].toLowerCase();
const command = commands.get(name) || commands.find(c => c.aliases && c.aliases.includes(name));
if (!command) {
return message.reply('that\'s not a valid command!');
}
data.push(`**Name:** ${command.name}`);
if (command.aliases) data.push(`**Aliases:** ${command.aliases.join(', ')}`);
if (command.description) data.push(`**Description:** ${command.description}`);
if (command.usage) data.push(`**Usage:** ${prefix}${command.name} ${command.usage}`);
data.push(`**Cooldown:** ${command.cooldown || 3} second(s)`);
message.channel.send(data, { split: true });
},
};
The error:

How to remove a role when getting another(discord.js)

All that I got was just this one (there, when writing (! +), He fulfills the role, but even then she is a non-worker, please help)
bot.on('message', msg => {
if (msg.content === prefix + '+') {
member.roles.remove(801095844044341279).catch(console.error);
}
});
knocks out this error
C:\Users\user\Desktop\bot\index.js:40
member.roles.remove(801095844044341279).catch(console.error);
^

You need to use the Message object to get the member from it.
Like this:
bot.on('message', msg => {
if (msg.content === prefix + '+') {
msg.member.roles.remove('801095844044341279').catch(() => {
console.error("failed to remove role");
});
}
});
I also fixed your console.error as it was invalid syntax, if it fails to remove the role it will error to the console properly now.

(Discord.js) TypeError: Cannot read property 'add' of undefined

So here's the code:
const mutedRole = message.guild.roles.cache.find(role => role.name === "Muted");
if (!mutedUser) return message.channel.send()
if (!message.author) return;
if (!mutedRole) {
message.guild.roles.create({
data: {
name: 'Muted',
color: '#6C877C',
permissions: ["CREATE_INSTANT_INVITE", "VIEW_CHANNEL"],
},
})
.catch(console.error);
}
mutedUser.roles.add(mutedRole).catch(console.error);
When I run the bot, I get the error:

As seen on the code, I add the part where the bot would make a role as when the role is unavailable. But still, it thinks as that the role never exist.
Before this was copied, I aslo wrote the code like this:
if (!mutedRole) {
guild.roles.create({
data: {
name: 'Muted',
color: '#6C877C',
permissions: ["CREATE_INSTANT_INVITE", "VIEW_CHANNEL"],
},
})
.catch(console.error);
}
And the result is still the same. I also put the bot's role on the most top list of all roles on my test server. Can anyone find out why?
I'm currently using discord.js v12 and stable version of node.
Note: full code here: https://github.com/centralomd/breadbot/blob/master/commands/mute.js

The error comes from line 14:
const mutedUser = message.mentions.users.first() || message.guild.members.get(args[0])
If there are no mentions in the message.mentions.users Collection, you are trying to get a GuildMember using message.guild.members.get().
Discord JS v12 introduces the concept of managers, you will no longer be able to directly use Collection methods such as Collection.get() on data structures like Client.users and Guild.members.
You'll have to change it with:
const mutedUser = message.mentions.users.first() || message.guild.members.cache.get(args[0])
if (!mutedUser) return message.channel.send("Invalid user.");
Note: message.mentions.users will get users in other guilds as well. I recommend you to use message.mentions.members.

TypeError: value.split is not a function

I'm creating a discord.js bot v12 and I get this error on line 2 when I use the purge command in discord and I'm assuming value.split is not a function and wondering if I should be doing something else since I'm using v12 of discord.js:

This is my code:
module.exports.run = async (client, message, args) => {
let [ userId, limit ] = args.split(/\s+/);
if(!userId && !limit) {
let deletedMessages = await message.channel.bulkDelete();
message.channel.send(`${deletedMessages.size} messages were deleted.`);
}
if(!userId || !limit) return message.channel.send('Please provide the correct arguments.');
let r = new RegExp(/^\d+$/);
if(!r.test(userId)) return message.channel.send('Please provide a valid user id.');
if(isNaN(limit)) return message.channel.send('Please provide a numeric value for limit');
if(limit > 100) return message.channel.send('Limit must be less than or equal to 100.');
try {
let fetchedMessages = await message.channel.messages.fetch({ limit });
let filteredMessages = fetchedMessages.filter(message => message.author.id === userId);
let deletedMessages = await message.channel.bulkDelete(filteredMessages);
message.channel.send(`${deletedMessages.size} messages were deleted.`);
}
catch(err) {
console.log(err);
}
}
module.exports.help = {
name: "purge",
description: "Deletes a number of messages from a user in a channel."
}
module.exports.requirements = {
userPerms: [],
clientPerms: [],
ownerOnly: false
}

It seems that args is not type of string. When you call .split() for something other than a string, JavaScript runtime cannot find the .split() method for that type. So, make sure you are passing a string to your function or try something like that:
if (typeof string === args) {
var str = args.toString();
}

Turns out I needed to replace value.split to value.slice

Discord.js Bot crashing while used command

my problem is when i write command! Tempmute (user) (time) and in field (time) i'll write for example 10 s / m / h / d it works great but when i wrote other letter in this field bot just crash.
Can any one tell me how to fix it? Thanks in advance!
Code:
if (command === `${prefix}tempmute`) {
let tomute = message.guild.member(message.mentions.users.first() || message.guild.members.get(args[0]));
if(!tomute) return message.reply("Nie moge znaleźć określonego użytkownika");
if(tomute.hasPermission("ADMINISTRATOR")) return message.reply("Ta osoba ma zbyt wysoką rangę lub nie masz permisji!");
let muterole = message.guild.roles.find(r => r.name === "muted");
if(!muterole){
try {
muterole = message.guild.createRole({
name: "muted",
color: "#0000000",
permissions: []
})
message.guild.channels.forEach(async (channel, id) => {
channel.overwritePermissions(muterole,{
SEND_MESSAGES: false,
ADD_REACTIONS: false
});
});
} catch(e) {
console.log(e.stack);
}
}
let mutetime = args[1];
if(!mutetime) return message.reply("Wprowadź czas na jaki ma byc zmutowana osoba")
tomute.addRole(muterole.id);
message.reply(`<#${tomute.id}> został zmutowany na ${ms(ms(mutetime))}`);
setTimeout(function(){
tomute.id.removeRole(muterole.id);
message.channel.send(`<#${tomute.id}> został odmutowany!`);
}, ms(mutetime));
}
}
);

Add your code to the try catch statement it won't crash anymore, but if you want to check if the argument corresponds to what you want, you can make an regexp
try catch:
try
{
}catch(error)
{
console.log(error)
}
Regex:
var match = /^(-?(?:\d+)?\.?\d+) *(milliseconds?|msecs?|ms|seconds?|secs?|s|minutes?|mins?|m|hours?|hrs?|h|days?|d|weeks?|w|years?|yrs?|y)?$/i.exec(
mutetime);
if(!match)return;
