I'm making a command for my discord bot and i get the error "This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:
TypeError: this.client.incrementMaxListeners is not a function
at new MessageCollector" which i barely understand
