Well I don’t know js library but in .NET this is your problem. I hope u get some idea.
I am pretty sure this is happening because the message is of the type SocketMessage
and not SocketGuildMessage
. Cast message
into SocketGuildMessage
and you will be able to leave the guild easily. It doesn’t matter if you are on the server or not.
