The Plugin don't work in 1.15.2

Each time I try to do the /sp or /splegg command it tells me : An internal error occured while attempting to perform this command
If you have any idea of how to make it work It would be very cool !
( This plugin is the only splegg plugin that I found and it's too complicated to do with command block x) )

The Plugin don't work in 1.15.2

Why in heaven's name do you think it would? MinigamesAPI and the associated games were abandoned three years ago, when Spigot was 1.12.2.
