Sending message to specific channel based on an argument

Tags: , , ,

I have searched up and found multiple forum posts on both Reddit and StackOverflow where users are asking how to send a message to the specific channel, but I cannot find one where you can send to a specific channel using an Argument. What I mean is that you use

return bot.channels.get(channel).send(embed);

I have been testing around with this “function” and have managed to send the message to a specific channel, but it also includes the arg[0] aka the channel id. The command is


It does send the embed with the message to that specific channel I input, but It adds the CHANNEL ID to the embed, so I tried to use arg[0] in the embed’s .setDescription(arg[0]) but it didn’t work. It spat out an error message to me which I have no idea what means. But maybe one if you pro’s out there know what I can do. Here is the entire command Code:

if (cmd === `${prefix}announce`) {
  console.log( + " executed an Announcement in the channel #" +;
  const embed = new Discord.RichEmbed()
    .setAuthor("Announcement from " +,

  return bot.channels.get(channel).send(embed);

And here is the error code. Note that the error only pops up when I put arg[0] in the .setDescription() part of the embed. The channel let works fine with arg[1]

You could use the message.mentions property. So you would do the following:

let announceChannel = message.mentions.channels.first();

Then to send the message do the following; message.guild.channels.find(t => ==;
