MCAuthenticator not working on bungee 1.13 with Viaversion 1.4.0 and up

As the title states, MCAuthenticator does not work on bungee 1.13 with Viaversion of 1.4.0 and up.

The following stack trace is thrown when typing in chat or running a command, after which the player gets booted: https://hastebin.com/pisocadumu.md

The stack trace no longer exists, but most likely you needed to put a colon in the channel name in the config, so for example "MCAuthenticator:Auth" as opposed to "MCAuthenticator".

Edit: Turns out it has to be lowercase, so "mcauthenticator:auth" instead.
