DiscordAPIError: Cannot send an empty message (discord.js v13) - discord.js

Question

I am coding a bot with the below command and it throws an error, but i don't know where is the error
i tried my best
const Discord = require("discord.js");
const client = new Discord.Client({
allowedMentions: {
parse: ["roles", "users", "everyone"],
},
intents: [
Discord.Intents.FLAGS.GUILDS,
Discord.Intents.FLAGS.GUILD_MESSAGES,
Discord.Intents.FLAGS.DIRECT_MESSAGES
]
});
const config = require("../config.json");
module.exports = {
name: "quar",
run: async (client, message, args) => {
if (!message.member.permissions.has("ADMINISTRATOR")) return;
let role = message.guild.roles.cache.find(role => role.name === "Quarantined" || role.name === "Quarantine")
let member = message.mentions.members.first() || message.guild.members.cache.get(args[0])
let reason = message.content.split(" ").slice(2).join(" ")
if(!reason) reason = "No reason given."
if(!role) return message.channel.send("❌ This server doesn't have a quarantine role!")
if(!member) return message.channel.send("❌ You didn't mention a member!")
if(member.roles.cache.has(role.id)) return message.channel.send(`❌ That user already quarantined!`)
member.roles.add(role)
.then (() => {
const embed = new Discord.MessageEmbed()
.setTitle(`✅ ${member.user.tag} was quarantined!`)
.setColor("RANDOM")
.setTimestamp()
embed.setFooter(`Requested by ${message.author.username}`)
message.channel.send(embed)
member.send(`You were quarantined in \`${message.guild.name}\`. Reason: ${reason} `).catch(error => {
message.channel.send(`❌ Can't send DM to ${member.user.tag}!`);
});
})
}
}
If I have made a mistake, please help me out
Sorry I don't speak English well

Try the below code out, I made notes along the way to explain as well as improved a small bit of code. I assume this is a collection of 2 separate files which is why they are separated. If they aren't 2 separate files, you do not need the top section, just the bottom.
const {
Client,
Intents,
MessageEmbed
} = require("discord.js");
const client = new Client({
allowedMentions: {
parse: ["roles", "users", "everyone"],
},
intents: [
Intents.FLAGS.GUILDS,
Intents.FLAGS.GUILD_MESSAGES,
Intents.FLAGS.DIRECT_MESSAGES
]
});
const config = require("../config.json");
const {
MessageEmbed,
Permissions
} = require("discord.js");
module.exports = {
name: "quar",
run: async (client, message, args) => {
if (!message.member.permissions.has(Permissions.FLAGS.ADMINISTRATOR)) return;
let role = message.guild.roles.cache.find(role => role.name === "Quarantined" || role.name === "Quarantine")
let member = message.mentions.members.first() || message.guild.members.cache.get(args[0])
let reason = message.content.split(" ").slice(2).join(" ")
if (!reason) reason = "No reason given."
if (!role) return message.channel.send("❌ This server doesn't have a quarantine role!")
if (!member) return message.channel.send("❌ You didn't mention a member!")
if (member.roles.cache.has(role.id)) return message.channel.send(`❌ That user already quarantined!`)
member.roles.add(role)
.then(() => {
const embed = new MessageEmbed()
.setTitle(`✅ ${member.user.tag} was quarantined!`)
.setColor("RANDOM")
.setTimestamp()
.setFooter({
text: `Requested by ${message.author.username}`
})
// author and footer are now structured like this
// .setAuthor({
// name: 'Some name',
// icon_url: 'https://i.imgur.com/AfFp7pu.png',
// url: 'https://discord.js.org',
// })
// .setFooter({
// text: 'Some footer text here',
// icon_url: 'https://i.imgur.com/AfFp7pu.png',
// })
message.channel.send({
embeds: [embed]
}) //embeds must be sent as an object and this was the actual line that was causing the error.
member.send(`You were quarantined in \`${message.guild.name}\`. Reason: ${reason} `).catch(() => { // if error is not used, it is not required to be stated
message.channel.send(`❌ Can't send DM to ${member.user.tag}!`);
});
})
}
}
