For the last 3 hours I've been trying to get this plugin to work, I've installed it with the other plugin dependencies and keep getting error message after error message. I've input all the ID numbers required, set up the bot and entered all that information and yet still getting red errors. I've even put it back to previous versions of the plugin to see if that would correct it and nothing. The error I keep getting is: failed to call hook 'ondiscordgatewayready' on plugin 'DiscordCallAdmin v1.0.0'(I get this same error regardless of version) (NullReferenceException: Object reference not set to an instance of object)

Please post the full error from the logs.
