I have a problem with my server, when I try to put a protection, I get an error in the console (attached photo)
I realized that if you uninstall WorldGuard this error is removed and everything is normal, how can I fix it?
Now I have on my Spigot 1.12.2 server these versions of plugins
Vault 1.7.1
WorldEdit 6.1.9
WorldGuard 6.2.2
Precious stones: 10.7.2
