One reason why this error could be coming is because there is no property called as client.owner in a Client . But one way, you could use client.owner is if you created a Collection and then set it to an array. An example would be like this:

import { Collection } from 'discord.js'
// ...
client.owner = new Collection()
const ownerArray = [{
    username: '',
    id: ''
}] // Use something like a hardcoded value for the array of owners
ownerArray.forEach(owner => {
    client.owner.set(owner.id, owner.username)
})
// ...
