Embed: DiscordAPIError: Cannot send an empty message

It's me again..

Alright so:

I'm trying to make a command that will warn users they joined a wrong server, But when I run the command, I get the Cannot send an empty msg error..

Really, any help would be appreciated!

const Discord = require("discord.js")

module.exports.run = async (client, message, args, err) => { 
const embed = new Discord.MessageEmbed().setTitle('Hey!').setDescription('We think you have our server mistaken. etc etc')
     if (!args[0]) return message.reply('Who?', { allowedMentions: { repliedUser: false } });
     const member = message.mentions.members.first() || await message.guild.members.fetch(args[0]).catch(e => {
      check = true;
      return message.reply('Can\'t find specefied member! Provide a valid ID, or mention ig lol.', { allowedMentions: { repliedUser: false } });
    });
    message.channel.send(embed).catch(err)
    message.channel.send(`${member}`)
    }

Error:
