I looked into it and found that when I run /dwatest in-game it states "[11/29/2019 4:05:52 PM] [DiscordMessages] Failed! Discord responded with code: 400. Plugin: Unknown Plugin
{"message": "Cannot send an empty message", "code": 50006}"

I haven't tried rebooting the server as it just wiped and people are one, so I don't know if this will occur again after restart but, all my other stuff works fine?
