Why am I getting an error fetching messages?

Question

there is an error calling the script. Can you ask for help?

Below I paste the code and the error.

let chn = client.channels.find(channel => channel.id === '717019301357420554');
let msg = chn.fetchMessage('717369584801546273');
msg.edit(embedit);

TypeError: msg.edit is not a function

Answer 1

Is this v11?

Regardless fetching something is async, so you need to wait for msg to resolve.

https://discord.js.org/#/docs/main/11.1.0/class/TextChannel?scrollTo=fetchMessage

Here's how you can go about it:

First one is using await which needs to be inside of an async function

let chn = client.channels.find(channel => channel.id === '717019301357420554');
let msg = await chn.fetchMessage('717369584801546273');
msg.edit(embedit);

Second is .then

let chn = client.channels.find(channel => channel.id === '717019301357420554');
chn.fetchMessage('717369584801546273').then(msg => msg.edit(embedit));

If you want to save it in a variable

let chn = client.channels.find(channel => channel.id === '717019301357420554');
let msg;
chn.fetchMessage('717369584801546273').then(m => msg = m);
//note you will have to wait for the promise to resolve to use 
//the variable msg correctly
//any code beyond this isn't guranteed to have access to 

These are some bad variable names btw, you shouldn't use abbreviations like chn rather channel, and embedit => embEdit. But up to you
