Legacyload skywars map error

[lapis pike]

Hello, I have a problem executing the /swmap legacyload (mapname) command as these errors appear in the console, and then it takes me out of the server.

I am using version 1.19.2 of PaperSpigot
SkyWars version: 5.6.12
Error log: https://pastebin.com/C7USnwKx

it tells you it's not an error

just means that the server took a while to run it

which is normal when loading a map
