What I am trying to do: Look, what I'm trying to do is to make it so there is more than 1 server in an embed and buttons that goes left and right. Here is an example of how the embeds should look like:
Blacklisted Servers
(1st Server ID) (Reason of Blacklist) ----------------------- (2nd Server ID) (Reason of Blacklist)
and so on.
Solution
Change messageRun for chatInputRun. You're mixing message based and slash commands.
