TypeError: message.author is not a function

For this piece of code, I aim for the author of the message that sent the ban command to be checked for whether they have the permissions necessary to ban the member, instead of instantly being allowed to, however I am unsure of what the const mod should be equivalent to to do so. Any help would be appreciated, thanks.
module.exports = {
name: 'ban',
description: "This command ban a member!",
execute(message, args) {
const target = message.mentions.users.first();
const mod = message.author();
if (mod.hasPermission('BAN_MEMBERS')) {
if (target) {
const memberTarget = message.guild.members.cache.get(target.id);
memberTarget.ban();
message.channel.send("User has been banned");
}
} else if (mod.hasPermission(!'BAN_MEMBERS')) {
message.channel.send(`You couldn't ban that member either because they don't exist or because you dont have the required roles!`);
}
}
}

As it says, Message.author is not a function. It is a property. You access it without the brackets
const mod = message.author
Another problem you may get is you can't get permissions. You will need Message.member for that
const mod = message.member

TypeError: Cannot read property 'roles' of undefined in discord.js

I am trying to get the bot to add roles in one discord and also add a role in another discord. but I keep getting the "roles" is not defined error. I have little to no coding knowledge and most of my code is a combination of things I find on google or friends teach me, so please excuse me if it is a dumb problem with a simple solution.
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES, Intents.GUILD_ROLES] });
module.exports = {
name: 'accept',
description: 'Adds A Player To The Whitelist',
permissions: `ADMINISTRATOR`,
execute(message, args, add, roles, addRole, guild) {
message.delete()
let rMember = guild.roles.cache
message.mentions.members.first() || // `.first()` is a function.
message.guild.members.cache.find((m) => m.user.tag === args[0]) ||
message.guild.members;
let role1 =
message.guild.roles.cache.find((r) => r.id == roleID)
let role2 =
message.guild.roles.cache.find((r) => r.id == roleID)
let server = client.guilds.cache.get('guild ID')
let memberRole = server.guild.roles.get("role ID");
rMember.roles.add(role1).catch((e) => console.log(e));
rMember.roles.add(role2).catch((e) => console.log(e));
rMember.roles.add(memberRole).catch((e) => console.log(e));
rMember.send(`message content`);
message.channel.send('message content')
}};
The error occurs in this line:
let memberRole = server.guild.roles.get("872432775330955264");

let server = client.guilds.cache.get('guild ID')
let memberRole = server.guild.roles.get("role ID");
These particular lines justify your error, in the first case you are assigning the property of a guild object to server by getting the guild from the cache, now you see a guild object does not have a property further named guild to it so your error actually rests in the next line, where you are trying to get from server.guild it's same as saying guild.guild which makes no actual sense.
Only correction you would want to make with your code would be something of this sort:
let server = client.guilds.cache.get('guild ID')
let memberRole = server.roles.cache.get("role ID");

Discord.js mod bot ban command not working

My discord bot's ban command isn't working and is currently giving me this error. My rols id is 853527575317708820
I don't know what I am doing wrong so please help me out
Here is the command :
Server is ready.
TigerShark Community#3557 Has logged in

Here is my code :
module.exports = {
name: 'ban',
description: "Used to ban members from a server",
async execute(client, message, args, Discord) {
if (!(message.member.roles.cache.some(r => r.id === "853527575317708820"))) return
let reason;
const user = await client.users.fetch(args[0])
if (!args[1])
{
reason = "Not specified"
} else {
reason = args[1]
}
const embed = new Discord.MessageEmbed()
.setTitle(`${user.username} was banned!`)
.setDescription(`${user.username} was banned by ${message.author.username} for: ${reason}`)
.setColor("#f0db4f")
.setFooter("Ban Command")
.setTimestamp()
message.channel.send(embed)
message.guild.members.ban(user)
}
}

Your command has few issues in it.
The first being that it does not allow banning users with command if the user is mentioned, it only allows banning by user ID. To fix that simply do:
const user = message.mentions.members.first() || await client.users.fetch(args[0])
You should also add check if the user is found, so right after you declare value for user
const user = message.mentions.members.first() || await client.users.fetch(args[0])
if(!user) return message.reply(`No user found`);
Now if you allow banning both mentions and user IDs there might be a different user value. So I recommend editing your embed aswell to something like:
const embed = new Discord.MessageEmbed()
.setTitle(`${user.user.username} was banned!`)
.setDescription(`${user.user.username} was banned by ${message.author.username} for: ${reason}`)
.setColor("#f0db4f")
.setFooter("Ban Command")
.setTimestamp()
This should fix majority of your issues, I recommend that if something is undefined in future or you come across any bugs in your code. Do some debugging by sending messages to console console.log(variable) or console.log("This works?")

if you are using discord.js v12 you can do what the other answer said and get the user by mention message.mentions.members.first() but if you are using v13 that wont work anymore
the reason its giving that error is because you need to fetch the user by their id alone, so you can do this client.users.fetch(args[0].replace('<#!', '').replace('>', '')) to remove the <#! and > (mention prefix) from it.

invite Created event

so I'm making a Discord Bot, with auto logging capabilities, until now I managed due to do most of the code, these include the command for setting a mod-log channel and the event code, here's the code for the command:
let db = require(`quick.db`)
module.exports = {
name: "modlog",
aliases: ["modlogs", "log", "logs"],
description: "Change the modlogs channel of the current server",
permission: "MANAGE_CHANNELS",
usage: "modlog #[channel_name]",
run: async (client, message, args) => {
if(!message.member.hasPermission(`MANAGE_CHANNELS`)) {
return message.channel.send(`:x: You do not have permission to use this command!`)
} else {
let channel = message.mentions.channels.first();
if(!channel) return message.channel.send(`:x: Please specify a channel to make it as the modlogs!`)
await db.set(`modlog_${message.guild.id}`, channel)
message.channel.send(`Set **${channel}** as the server's modlog channel!`)
}
}
}
And the inviteCreate event:
client.on("inviteCreate", async invite => {
const log = client.channels.cache.get(`${`modlog_${message.guild.id}`}`)
let inviteCreated = new Discord.MessageEmbed()
log.send(`An invite has been created on this server!`)
})
The issue is that since the inviteCreate event only accepts one parameter (I think that's what they are called) which is invite, there is no message parameter, so message becomes undefined, does anyone have a solution?
Thanks!

You don't need message in this case. See the documentation of invite.
Your message.member can be replaced with invite.inviter
Your message.channel can be replaced with invite.channel
Your message.guild can be replaced with invite.guild

Invites also have a guild property, that's the guild the invite is for, so you can use that instead of the message.guild:
client.on('inviteCreate', async (invite) => {
const log = client.channels.cache.get(`${`modlog_${invite.guild.id}`}`);
let inviteCreated = new Discord.MessageEmbed();
log.send(`An invite has been created on this server!`);
});

How to log into the ban section of discord using discord.js v12?

I'm working on my ban command and it's fully functional, but I was wondering, how I would log the ban reason into the ban section of discord (example in the attachment)? My code looks like this:
const { DiscordAPIError } = require("discord.js");
const Discord = require('discord.js');
module.exports = {
name: 'ban',
description: "Mentioned user will be banned",
execute(message, args){
if (!message.member.hasPermission("BAN_MEMBERS")) return message.channel.send("Invalid Permissions")
let User = message.guild.member(message.mentions.members.first()) || message.guild.members.cache.get(args[0])
if (!User) return message.channel.send("Invalid User")
if (User.hasPermission("BAN_MEMBERS")) return message.reply("Invalid Permissions a")
let banReason = args.join(" ").slice(22);
if (!banReason) {
banReason = "None"
}
console.log(`USER = ${User}`)
User.ban
console.log(`Ban reason = ${banReason}`)
var UserID = User.id
console.log(`USER ID = ${UserID}`)
}
}
Any help? Thanks :)

It's actually quite easy, just add ({reason: banReason}) after the User.ban part, making it:
User.ban({reason: banReason})
That should log it there properly :)

You can use the reason property of the options parameter in the GuildMember.ban() method:
User.ban({ reason: 'real life danger' })
.then(member => console.log(`${member.name} was banned.`))
.catch(console.error)
Also, in your code, there's no reason for using the Guild.member() method when defining User. Guild.member(user) is used to turn a User object into a GuildMember object.
However, MessageMentions.members.first() already returns a GuildMember object, making it obsolete.
