javascript - How to make my discord.js-bot log the edit of a message?

Question

I'm trying to make my bot log when and what has been edited in a message.

This is the code of the listener:

client.on('messageUpdate', (oldMessage, newMessage,message) => {
    client.on('messageUpdate', (oldMessage, newMessage,message) => {
const MessageLog = client.channels.cache.find(channel => channel.id ==='802262886624919572');
var embed = new Discord.MessageEmbed()
.setAuthor(message.author.username).catch(console.error)
.setTimestamp(new Date())
.setColor('#392B47')
.addFields(
    {name: 'original:',value: oldMessage},
    {name: 'edit:', value: newMessage}    );
MessageLog.send(embed);
 });

Answer 1

The error message says that message is undefined. The problem is that the messageUpdate event doesnt give the last message as a parameter (https://discord.js.org/#/docs/main/stable/class/Client?scrollTo=e-messageUpdate) To fix this you could replace the message in message.author.username with newMessage.

I also found another problem with your code, when you add the fields to the embed, you should use newMessage.content as the value, instaid of just newMessage
