Can't generate invite link

[durstam]

I've input the Bot Owner ID, Bot Token and Client ID after creating the file in Bot Maker and making the application on the Discord website, but when I click on the link to invite the bot to a test server, I get "UNKNOWN_ERROR". Haven't started adding any commands or anything to the bot, I don't wanna put all that effort in if I can't get the bot onto a server.
