and i get this error:

client.channels.cache.get(db.get(args[1])).send(args[2]);
                                                ^

I'm guessing that db.get() returns a promise which you cannot pass as a value. Try retrieving the value first and then get the channel. Something like

const id = await db.get(args[1]);
const channel = client.channels.cache.get(id);
channel.send(args[2]);

There is also a possibility that the id is stored incorrectly in your server. So have a look at that. You could log the id to check if that is the case.
