How to get username from client id after the user has left the guild

I have: bot.users.get(id) but when user leave the server an error pops up. Can I get the username with the ID differently if the user is not on the server?
I have statistics. I am downloading from the User Id database and I am replacing the ID with its name, but if the user has left the server, there is an error because there is no such user. What can I do?

Since client.users stores only cached users, you won't be able to retrieve their username in a reliable way from there.

client.users

DISCLAIMER: This method is really inefficient, but discord.js hasn't been made for this kind of work. If you want to make it easier, just write Unknown user (client_id)

Unknown user (client_id)

If you're not able to get the username from a user list you could try to use messages: use channel.fetchMessages() on every channel of your guild until you find a message in which message.author.id == your_id, when you find it you can get the username with message.author.username

channel.fetchMessages()

message.author.id == your_id

message.author.username

There's also another solution: a self-bot. Keep in mind that this one is not supported by Discord itself, and could result in a permanent ban for the account you're using.
With that said, if you use a self-bot you can use the TextChannel.search() method to quickly find a message with your author id and then grab the username from the author.

TextChannel.search()
